What makes RTC different? 2x the amount for PTs RTC provides most ampuled water PTs in duplicate. This allows you to run multiple methods or have more analysts perform the PT. It also covers your laboratory in case of the accidental mishap. If you do not use the second vial, it becomes a QC sample once the study is closed. Easily Accessed Documentation Online Certificates of Analysis, MSDS, and Proficiency Testing reporting documents can easily be viewed and downloaded through our website. RTC Quick-Turn Studies RTC does not charge extra for our Quick-Turn PT studies. Our Quick-Turn studies are always the same price as our scheduled PTs. The World Standard Standardized QC Pricing RTC has a straightforward and logical pricing scheme for its QC products. Our QCs are always 30% less than our PT products. Certificates of Excellence Laboratories that demonstrate excellence throughout the year in proficiency testing are issued a certificate suitable for display and presentation to your customers. Analyst Certificates of Proficiency Laboratories that enter data online are able to generate and print a certificate of proficiency for each PT the analyst has successfully performed. These certificates represent valuable records of training and performance for laboratory audits. 2 First Choice for Quality

Matrix Modifier Materials All of RTC s water standards produced are classified as very soft water in respect to the water hardness scale. As ISO 17025 accreditation has spread throughout the world, the demand for a matrix matched standard with local water characteristics has also risen. RTC has stepped up to the challenge and introduced specific water matrix modifiers to use in conjunction with its samples to assist labs in simulating the most realistic water sample they deal with every day. Units used to measure water hardness: Hardness CaCO3 mg/l CaCO3 mg/l Degrees Clarke Degrees French Degrees German Soft <30 <75 <5.3 <7.5 <4.2 Moderately Hard 30 60 75 150 5.3 10.5 7.5 15 4.2 8.4 Hard 60 120 150 300 10.5 21 15 30 8.4 16.8 Very Hard >120 >300 >21 >30 >16.8 RTC has developed a range of matrix modifiers that allow most existing RTC PT and QC standards to be prepared so that the matrix can be set any of the following levels: 100 mg/l CaCO 3 200 mg/l CaCO 3 400 mg/l CaCO 3 Moderately Hard Water MML001-20ML A single concentrate for dilution to 2L MML001-5x20ML 5 Concentrates for dilution to 10L Hard Water MMM001-20ML A single concentrate for dilution to 2L MMM001-5x20ML 5 Concentrates for dilution to 10L Very Hard Water MMH001-20ML A single concentrate for dilution to 2L MMH001-5x20ML 5 Concentrates for dilution to 10L Moderately Hard Water Hard Water Very Hard Water Two further Matrix Modifiers are available: Waste Water to produce typical discharge water that is tinted and contains particulates and Salt Water to replicate sea or estuarine waters. Waste Water can be used together with any of the Hard Water modifiers and Waste and Salt Waters may be combined. Each modifier is supplied as a concentrate that will prepare 2L of matrix water that is used to make up the chosen RTC PT or QC standard. Standards are supplied with a data sheet indicating analytes that are incompatible with the matrix.

Rapid Check (RQC) Daily Use Bacterial QCs RapidCheck microbiological standards are designed with the microbiology laboratory in mind by enhancing quality and reducing costs. RTC s RapidCheck microbiological standards utilize Vitroid technology, ensuring that our standards deliver a quantified dose of organisms sourced from internationally recognized repositories. Each Vitroid is a Certified Reference Material (CRM) that readily fits into most organization s procedures without modification. Dosages are designed to deliver convenient bacterial quantities without additional dilutions. RapidCheck products are certified for use in both Quantitative and Qualitative methods. RapidCheck s single use format reduces contamination risks within the laboratory. Analysts no longer need to maintain stock cultures or purchase costly standards. Vitroid Technology This technology for stabilizing micro organisms minimizes the stress during the storing process. This technology offers significant advantages over other stabilization technologies. Unlike other microbiological standards, RTC s Vitroid based products offer: 1) Enhanced long term stability; 2) High organism viability; and 3) No Recovery or Pre-incubation time. This means RTC s products are easier and faster to use, saving the busy laboratory analysts time. Vitroids are small highly soluble tablets that can easily be implimented into the laboratories procedures with little or no modification. Each Vitroid can be solubilized in as little as 100 µl of any aqueous solution or even solubilized directly on the surface of a media plate. Upon the solubilization of the Vitroid the standard is ready to be used, no recovery or pre-incubation is required prior to use. Each Vitroid delivers a quantified dose of organisms backed by ISO Guide 34:2009 accreditation in conjunction with ISO/IEC 17025:2005 accreditation. Many of RTC s RapidCheck microbiological standards are offered as Quality Control microbiology products under the American Type Culture Collection (ATCC ) Licensed-Derivative program. Look for the ATCC Licensed-Derivative Emblem for products derived from ATCC cultures. The ATCC Licensed Derivative emblem signifies ATCC-derived products are endorsed by ATCC. Products displaying the emblem are the only ones for which the quality of the ATCC ingredient can be properly assured. ATCC does not endorse products including ATCC ingredients from companies that are not members of the LDP program. 46 First Choice for Quality

Easy To Use Levels Offered RapidCheck products are easy and convenient to use. The RapidCheck Vitroid is readily solubilized in any aqueous buffer, in as little as 100 μl of buffer. A Vitroid can even be spread directly on a culture plate! Typically, a Vitroid will absorb enough moisture in 15 minutes from a bacterial culture plate that an analyst can simply streak the microbiological standard using an innoculation loop and still achieve quantitative results. No other commercial microbiological standard offers so much diversity in use while maintaining its quantitative value. 50 cfu - Each Vitroid contains a single dose of 50 cfu * of the specified organism. The product is specifically designed so that no dilutions are required prior to use. Labeled as RapidCheck TM 50. 200 cfu - Each Vitroid contains a single dose of 200 cfu * of the specified organism. The product is specifically designed so that no dilutions are required prior to use. Labeled as RapidCheck TM 200. 1000 cfu - Each Vitroid contains a single dose of 1000 cfu * of the specified organism. This product is ideal for performing serial dilutions of 10, 1, and 0.1 mls or as high dosage negative controls. Labeled as RapidCheck TM 1000. RQC Simplified Ordering: To help our customers identify the products they need, RTC provides a convenient technology based organism list which states the most commonly used organisms used for that technology.

Natural-Matrix CRMs RTC is the world leader in manufacturing of real-world soil and sediment Certified Reference Materials (CRM). CRMs are produced and certified in compliance with ISO/IEC 17025 in conjuction with ISO Guide 34. Our CRMs are either Real World natural matrix or natural matrices in which selected analytes have been fortified to give analytical profiles that meet the needs of the market. A robust statistical program is used in determining the certified values of RTC CRMs, utilizing data developed from multi-laboratory analysis supported by in-house data. Most CRMs are method specific, and are supplied with certificates that show an uncertainty, expanded uncertainty, confidence interval, and a prediction value, in addition to the mean value and standard deviation from the mean. Certified Reference Material development started at RTC more than 23 years ago. Soils and solid wastes were collected from contaminated sites around the United States to produce real-world CRMs for the USEPA. Since then the product range has grown and now includes a wide range of natural-matrix CRMs. In close cooperation with regulatory agencies through out the Americas, Asia and Europe, RTC continues to develop new standards for proficiency testing schemes and CRMs to meet the needs of analytical laboratories around the world. Key factors when choosing and using a CRM: A CRM should have a representative selection of target analytes with certified values that fall into the normal range of the method. The matrix description should be similar to that of the test standards. The preparation method used for the standard should be similar to that for the CRM.

These CRMs were produced and certified from naturally contaminated matrices. Analytical data for Certification was obtained using USEPA SW846, 3rd edition methods 3050 (hot block) and 3051 (microwave) using nitric acid extraction. Analysis was carried out according to USEPA methods 6010 (ICP-EOS), 6020 (ICP-MS) and 7000 (AES). The standards are intended for use in analytical systems using these or similar methods. Note that nitric acid extraction is not as rigorous as aqua regia (see page 20), and these standards may not be suitable for method validation where an aqua regia extraction is used.

TCLP Metals - Soil The Toxicity Characteristic Leaching Procedure (TCLP) US EPA Method 1311, is intended to replicate the leaching of selected metals and organic compounds from materials placed into municipal landfills. If the extracted sample does not fail any of the analytes listed in the TCLP test, the material may be placed into a municipal landfill for disposal. For the determination of metals and semi-volatile organics, the procedure uses an extraction fluid (either #1 or #2) that is selected based on the initial ph of the sample. These extraction fluids are purposely designed to mimic the liquids that are produced in a municipal landfill from the infiltration of surface water. CRM It is imperative that the correct extraction fluid, based on the initial ph of the sample, be used. The use of the incorrect extraction fluid will give erroneous results.

California WET The following products were collected from Superfund (contaminated) sites in the Western United States and certified using USEPA SW846 3rd Edition method 1311 Toxicity Characteristic Leaching Procedure (TCLP) and the California Waste Extraction Method (WET). These methods are designed to replicate natural leaching from a contaminated site. Analysis of eight metals specified by the TCLP was carried out according to USEPA methods 6010 (ICP-EOS), 6020 (ICP-MS) and 7000 (AES). WET is an acronym for Waste Extraction Test and is used in the classification of metals as hazardous waste. WET is often used interchangeably with STLC or soluble when referring to the amount of a metal that is leachable, i.e. WET lead. The correct scientific nomenclature is CAL-WET or California Waste Extraction Test as defined in CCR Title 22. CRM Results of the WET are compared to the Soluble Threshold Limit Concentration (STLC). The WET determines the amount of a specific constituent that can be leached from the soil using a solution designed to simulate landfill leaching. The TCLP is a leaching procedure that uses a slightly less aggressive leaching agent than is used by the WET.

BNAs are a group of more than 60 organic compounds, including PAHs and related structures. The group is also commonly referred to as SVOCs. The analysis of BNAs is described in EPA Method 8270. RTC offers an extensive range of CRMs for BNA analysis, including sludges, sediments and all major soil types. These natural matrix CRMs were collected from various sites across the western United States. Analytical data for certification was obtained using USEPA SW846, 3rd edition extraction methods 3540B/3541 (soxhlet) and 3550A (sonication). Analysis was carried out according to USEPA method 8270 (Semi-volatile organics by GC/MS). The standards are intended for use in analytical systems using these and related methods.

The control of pollution caused by leaking underground fuel storage tanks is an increasingly important aspect of environmental analysis. For this reason, a comprehensive range of CRMs intended for method validation, method development or matrix recovery applications are available. This range of matrix CRMs was designed to include most common soil types and analytes found in fuels. They are supported by a comprehensive range of calibration standards, proficiency testing standards and Quality Control Standards. TPH is an acronym for Total Petroleum Hydrocarbons. It is a measure of the total amount of fuel present in the standard, i.e., TPHgasoline or TPH-diesel. TPH results can be quantified or calculated as either as specific fuels types, i.e. TPH as diesel, crude or gasoline, or as specific carbon ranges, i.e. C 10 -C 25. The following products are CRMs certified using data obtained by analysis using EPA Method 418.1, (TPH by Infrared) and are typical of contamination that is found in backfill soil surrounding a leaking underground storage tank.

The term chlordane refers to a complex mixture of chlordane isomers, other chlorinated hydrocarbons and by-products. In most temperate climates, only the two chlordane isomers, alpha and gamma chlordane, generally exist in the environment. The half-life of chlordane is more than 20 years. Toxaphene is a persistent organic insecticide and acaricide that is most often used in cotton cultivation. Toxaphene is not a single compound but a mixture of over 177 congeners, some of which are reported to change over time, depending on storage and ground conditions. The production of toxaphene was halted more than 20 years ago; however half-life of toxaphene in soil is believed to exceed 12 years.

PCBs PCBs, also referred to by the trade names Aroclor, Phenoclor and Kanechlor, are a family of chlorinated compounds that comprise 209 congeners, with different physical and chemical characteristics. Most PCB mixtures are oily liquids whose color darkens and viscosity increases with rising chlorine content. PCBs with fewer chlorine atoms are more soluble, more amenable to chemical and biological degradation, and less persistent in the environment than those PCBs with more chlorine atoms. PCBs are thermally stable and excellent electrical insulators. Chronic exposure of animals to PCBs can lead to disrupted hormone balances, reproductive failures, teratomas and/or carcinomas. A more significant health impact of PCBs may be caused by their incomplete combustion during thermal treatment processes. Incomplete oxidation of PCBs may form polychlorinated dibenzofuran (PCDF) dioxin emissions. These are of concern because of their toxicological and environmental properties. For the following CRMs analytical data for certification was obtained using USEPA SW846, 3rd edition extraction methods 3540B/3541 (soxhlet) and 3550A (sonication).

Constant Value - Water The need for CRMs for the validation and control of the analysis of water is steadily increasing as efforts to improve the quality of ground water and waste water increase. The production and distribution of natural-water CRMs are beset with particular difficulties, including maintaining sterility without altering the matrix, the weight of liter volumes of water and the associated packaging. One consequence of these difficulties is there are very few whole-volume natural water CRMs available. RTC has taken the procedures used to develop the range of water quality control RMs, which are supplied as concentrates, and used them to produce a range of water CRMs that suffer none of the problems associated with natural matrices. These standards have analytical values and uncertainties comparable with the best whole-volume water CRMs. Analytical data for certification was obtained using USEPA SW846, 3rd edition methods 3050 (hot block) and 3051 (microwave) using nitric acid extraction. Analysis was carried out according to USEPA methods 6010 (ICP-EOS), 6020 (ICP-MS) and 7000 (AES). All constant value water CRMs are supplied in concentrate form, and when diluted according to the instructions supplied, will give the certified values. But the analyst is free to dilute to larger, or smaller, volumes to give a particular value.

Special Section: Inorganic Traceable Reference Standards from Fluka Analytical Chemistry Certified Standard Solutions for AAS, ICP and IC produced under ISO/IEC 17025 and ISO Guide 34 Fluka s TraceCERT Inorganic Certified Reference Materials (CRM) are high accuracy standards for instrument calibration and process validation in spectroscopy and ion chromatography. These products are now available through RTC.

TraceCERT Traceable Certified Reference Materials TraceCERT inorganic CRMs are high accuracy standards for instrument calibration and process validation in spectroscopy and ion chromatography. Following lengthy cooperations with different metrological institutes, Sigma-Aldrich has built a new laboratory for Certified Reference Material (CRM) production and certification in Buchs, Switzerland. In 2007 the new lab received the highest achievable quality assurance level for CRM producers: double accreditation, as a testing lab following ISO/IEC 17025 and also as a CRM producer following ISO Guide 34. This combination is also called the Gold Standard accreditation for CRM producers and therefore we devoted the cover-page to our outstanding expertise. For all TraceCERT standards we guarantee: Highest accuracy and reliability of certified concentrations Traceability to at least two independent references (i.e. NIST, BAM or SI unit kg) Production in accordance with ISO/IEC 17025 and ISO Guide 34 Comprehensive certification according to ISO Guide 31 Competitive price What makes TraceCERT stand above the others? SRMS 001 ISO Guide 34 STS 490 ISO 17025 Elemental and ion standards are available from various suppliers. Why should I buy TraceCERT certified standards? Indeed many different standards are available covering a wide range in quality, service and price. As the world s number one in supplying research chemicals and standards, Sigma-Aldrich introduced TraceCERT reference materials to underpin its leading position in terms of quality and customer convenience. What makes TraceCERT standards higher in quality? Highest quality depends on many different technical and personal skills. These CRMs are produced and certified in accordance to metrological guidelines: highest accuracy, low uncertainties and in-depth documentation are what make TraceCERT products so reliable. These solutions are traceable to at least two independent references; NIST traceability is guaranteed whenever possible. In addition, we have extensive packaging knowledge and we guarantee all certified values until the bottle is in customer s hands. therefore, the first step to achieving correct measurement results. Our double accreditation according to ISO/IEC 17025 and ISO Guide 34 is an explicit affirmation of our competence to produce, certify and supply certified reference materials. Our customers can count on this competence and refer to it. We know: Buying analytical standards is a matter of trust. What about the price? These highest quality CRMs are competitively priced, compared to the products of other CRM manufacturers. When you check our website at www.sigma-aldrich.com/tracecert you will see that highest quality is not necessarily the most expensive. 16368-02 ISO 9001 What is the value of Sigma-Aldrich s double accreditation to the customer? Reliability! Every analytical laboratory will demonstrate the correctness of its measurement results. The use of accurate and well-documented standards is, 108 Special Section: Inorganic Traceable Reference Standards from Fluka Analytical Chemistry

Manufacturing Under Double-Accreditation The most accurate approach for the production of standards is high-precision weighing. Under ISO Guide 34 there is a particular focus on the quality of the starting materials and the entire manufacturing process including the choice of an the starting materials is assigned by the 100% minus impurities approach. Both approaches must lead to the same value within the range of their uncertainties. All starting materials are pretreated by surface etching or drying before they go to the high precision weighing room. Copper Silver Tin Gravimetric preparation using pure materials is a practical and the most accurate realization of concentration units. Highprecision weighing is a key step of the production, leading to direct traceability to the SI unit kilogram. The use of ultramicro balances with readability down to 100 ng in combination with a specially designed weighing room leads to maximum accuracy. Gold Silicium Cobalt Only materials of highest purity are used for the production of TraceCERT standards. The starting materials are characterized by two different approaches: the direct measurement of the purity by the most accurate method (e.g. titrimetry or high-precision ICP-OES). These measurements are compared to an internationally accepted reference material (i.e. NIST, BAM). In addition the purity of The weighted starting materials are dissolved in ultrapure acids or bases and then precisely diluted with ultrapure water to the final concentration. Also this operation is performed gravimetrically to achieve highest precision. Homogenization of the solution is achieved by overhead tumbling of the container for several hours. In the final bottling step, contamination is prevented by working under clean room conditions and by using PTFE-tubing and an inert peristaltic pump. After bottling, every batch is then compared to a second (whenever possible independent) reference material. Only when calculation and measurements are matching within their uncertainties (usually within 0.2-0.5 %) the batch is released for certification. Special Section: Inorganic Traceable Reference Standards from Fluka Analytical Chemistry 109

Certification and Comprehensive Documentation For each TraceCERT product, a detailed and comprehensive certificate is supplied, either delivered with the product (for the ICP standards) or downloadable from the Internet using product number and lot number (for the AAS and IC standards). Example certificates for every product can be downloaded from the Internet (www. sigmaaldrich.com/tracecert). The certificates are in accordance with ISO Guide 31 and contain lot specific information such as exact content, expiration date, traceability statements, values of up to 70 impurities (for ICP standards) and a proper uncertainty calculation. Uncertainty budgets are obtained by summing up all the contributing influence parameters ( bottom-up approach) and are illustrated by a cause-effect diagram. The certificates consist of up to four pages. See on the right the first page of certificate of the platinum ICP standard solution. TraceCERT Traceable Certified Reference Materials This certificate is designed in accordance with ISO Guide 31 [1]. Object of certification: Platinum standard for ICP Fluka product no.: 19078 (Lot 1371987, Filling Code 42208193) Composition: Platinum metal (high purity quality) in 5% HCl (prepared from HCl TraceSELECT, HNO3 TraceSELECT and water TraceSELECT Ultra, 18.2 MΩ. cm, 0.22 µm filtered) Density at 20 C: ρ = 1024.8 kg m -3 uc(ρ) = 0.5 kg m -3 Intended use: Calibration of ICP-spectrometry, AAS, spectrophotometry or any other analytical technique Storing and handling: This reference material shall be stored in the original closed bag between 5 C and 30 C. After opening the bottle should be stored at reduced temperature to minimize transpiration rate. Before every use of the material the bottle must be shaken well and its temperature has to be 20 C. We highly recommend using this reference material no longer than 15 months after the aluminum bag was opened. Expiry date: 8. May 2012 (unopened bottle in aluminized bag) Bottle opening date: Produced in double accredited laboratory fulfilling and ISO/IEC 17025 and ISO Guide 34 Certified value traceable to SI unit kg and uncertainty according to ISO Guide 35 [2] and Eurachem/CITAC Guide [3] [4]. Constituent Certified value at 20 C Expanded uncertainty [U = k uc; k = 2] Platinum 1001 mg L -1 977 mg kg -1-1 2 mg L 2 mg kg -1 1. CONCEPT OF CERTIFICATION AND TRACEABILITY STATEMENT To guarantee top reliability of the values for this TraceCERT certified reference material three independent procedures were followed. The values have to agree in the range of their uncertainties, but the impurity corrected value from the gravimetric preparation has been chosen as certified value [5] : 1. Gravimetric preparation using pure materials is a practical realization of concentration units, through conversion of masses and mole fraction to mass fraction [5]. If the purity of the materials is demonstrated and if contamination and loss of material is strictly prevented this approach allows highest accuracy and small uncertainties. The certified value of TraceCERT reference materials is based on this approach and directly traceable to the SI unit kilogram. Therefore comprehensively characterized materials of highest purity are used (see paragraph 2). All balances are certified by DKD and calibrated with OIML Class E2 (up to 12 kg) and F2 (up to 64 kg) weights. The bulk solution was homogenized by overhead tumbling in a PVDF container for at least 6 hours. A peristaltic pump with perfluorinated polymer tubings was used for bottling. Detailed information about the long-term stability of the bottled solution is given in paragraph 5 of this certificate. 2. The starting material is measured against a certified reference material (i.e. NIST, BAM or EMPA) followed by gravimetric preparation using balances calibrated with SI-traceable weights. Consequently the value calculated by this unbroken chain of comparisons is traceable to the reference to which the starting material is compared. 3. Whenever applicable the bottled TraceCERT calibration solution is compared to a second reference (e.g. from NIST, BAM or EMPA) which is independent from the first reference. Certificate page 1 of 3 Sigma-Aldrich Production GmbH, Industriestrasse 25, 9471 Buchs/Switzerland, Tel +41-81-755-2511, Fax +41-81-756-5449, e-mail: fluka@sial.com Packaging and Stability The ideal container for standard solutions is totally inert; i.e. will not absorb the analyte, does not leach impurities into the solution, is impermeable to the solvent and atmosphere and is easy to handle and affordable. For TraceCERT standards we have developed the most suitable container fulfilling all of these criteria: the HDPE bottles are extensively tested for leaching of impurities and the loss of weight by transpiration of the solvent was also investigated comprehensively. The results of this study are also stated in the certificate of each TraceCERT product. For maximum shelf life the bottles for ICP standards are sealed in aluminum bags to further prevent transpiration. Only this special packaging makes it possible to guarantee the ambitious specification of 0.2% uncertainty over the entire shelf life. 110 Special Section: Inorganic Traceable Reference Standards from Fluka Analytical Chemistry

In most cases, there is a responsibility to mitigate releases from leaking underground storage tanks (LUSTs) by reporting spills to authorities within a specified time and by promptly cleaning up any spills and discharges. Mitigation efforts are required to take place immediately to prevent further release (e.g., remaining products should be removed from the leaking tank), prevent the spread of contamination into soil and groundwater, and to investigate contamination. All of this has placed an increasing work load on analytical laboratories. At the same time the clean-up of old industrial, military and chemical industry sites has further increased demand for UST analysis. 2000 µg/ml in Methonol Benzene Ethylbenzene m-xylene 1-Methylnaphthalene Methyl tert-butyl ether n-decane n-dodecane n-hexane Unleaded Gasoline UST155-1.5ML 5000 µg/ml in Methanol UST145-1.5ML 5000 µg/ml in Methylene Chloride UST146-1.5ML 50000 µg/ml in Methylene Chloride W1366-1.5ML n-octane n-pentane Naphthalene 1,2,3-Trimethylbenzene o-xylene p-xylene Toluene Neat Collected from three sources and compounded prior to formulation.

Priority Pollutant Metals A list of 13 metals, Antimony (Sb), Arsenic (As), Beryllium (Be), Cadmium (Cd), Chromium (Cr), Copper (Cu), Lead (Pb), Mercury (Hg), Nickel (Ni), Selenium (Se), Silver (Ag), Thallium (Tl), and Zinc (Zn). Priority Pollutants Volatile Organic Compounds covered by EPA Method 8240. Purgeable Halocarbons Volatile Organic Compounds Covered by EPA Method 8010 and EPA Method 601. Also known as Chlorinated Solvents or Chlorinated Halocarbons. SIM Selected or selective ion monitoring. SIM Analysis sets the MS detector to repeatedly scan a few selected ions rather than a full spectrum. In the acquisition method (GC/MS SIM or Gas Chromatography/Mass Spectrometry using Selected Ion Monitoring), the selected ions are set to reflect the compounds to be detected. The detector scans for a primary, secondary and tertiary ion set unique to the compound of interest in a particular retention time window. SIMDIS Simulated distillation. It is expressed as the percentage of the total amount of TPH present in each Carbon Range. For example, if 100 ppm of TPH C 10 -C 40 is detected and 30 ppm lies in the C 10 -C 25 range then the percentage would be 30% C 10 -C 25 and 70% C 25 -C 40. SVOCs Semi-Volatile Organic Compound or BNAs (Base Neutral Acid) EPA Method 8270 describes the analysis of semi-volatile organic compounds using this technique. TCLP Toxicity Characteristic Leachate Procedure. Used to characterize the mobility of both organic and inorganic analytes present in liquid and solid wastes. An extraction method prescribed by CFR (Code of Federal Regulations.) The extraction process takes 18 hours. TPH Total Petroleum Hydrocarbons. A measure of the total amount of fuel present in the standard, i.e., TPH-gasoline or TPH-diesel. TPH results can be quantified or calculated as: Totals as specific fuels types, i.e. TPH as diesel, crude or gasoline Totals in specific carbon ranges, i.e. 500 ppm C 10 -C 25 VOAs Volatile Organic Analysis or Analytes. The term is now less used, having been replaced by VOC s. VOA Vials refer to the 40 ml containers used for aqueous sampling of volatile compounds. VOCs Volatile Organic Compounds. Refers to the list of analytes specified by EPA Method 8240 or the longer list specified by EPA Method 8260. MISC WET Waste Extraction Test and is used in the classification of metals as hazardous waste. It is often used interchangeably with STLC or soluble when referring to the amount of a metal that is leachable, i.e. WET lead. The correct scientific nomenclature is CAL-WET or California Waste Extraction Test as defined in CCR Title 22. ZHE Zero Headspace Extraction. A TCLP extraction method prescribed by CFR (Code of Federal Regulations) for Volatile Organic Compounds. 0 800.576.5690 rt-corp.com 307.745.7936 For mor information contact: RTeurope@sial.com 133
