In dspe, food or agricultural samples are first extracted with an aqueous miscible solvent (e.g., acetonitrile) in the presence of high amounts of salts (e.g., sodium chloride and magnesium sulfate) and/or buffering agents (e.g. citrate) to induce liquid phase separation and stabilize acid and base labile pesticides, respectively. Upon shaking and centrifugation, an aliquot of the organic phase is subjected to further clean up using SPE. In dispersive SPE, clean up is facilitated by mixing bulk amounts of SPE (e.g., CNWBOND PSA, Carbon-GCB, and/or HC-C18) with the extract. After sample clean up, the mixture is centrifuged and the resulting supernatant can either be analyzed directly or can be subjected to minor further treatment before analysis.

These manifolds permit consistent extraction and filtration results. Multiple sample processing with these manifolds simplifies procedures and saves time. The manifolds consist of a clear glass chamber and lid to which a vacuum is applied to draw a sample through an SPE column, cartridge, or disk. Adjustable racks placed in the glass vacuum chamber will accommodate a variety of sample collection vessels, including test tubes, autosampler vials, volumetric flasks, and Erlenmeyer flasks. Eluants are deposited directly into the collection vessel of choice via polypropylene, optional stainless steel, or Teflon needles. Drying attachments for the 12- and 24-port manifolds will direct a flow of air or nitrogen into the collection vessels to dry eluants prior to further analysis. Drying attachments can also be connected, via adapters, to SPE columns or cartridges in order to dry the column or cartridge prior to final elusion. Optional disposable solvent resistant polypropylene containers are available for the twelve port manifolds. These waste containers greatly simplify sample preparation, solvent disposal, and clean-up. 12 Position Vacuum Manifold Set-Complete 2.CR Includes: 1 glass chamber 1 cover, gasket, & 12 stopcocks 1 vacuum gauge & valve assembly 12 polypropylene needles Collection rack shelves, legs, clips, & posts 6 plates 1 waste container 1pcs 24-position Vacuum Manifold 16 Position Vacuum Manifold Set-Complete 2.CR Includes: 1 glass chamber 1 cover, gasket, & 16 stopcocks 1 vacuum gauge & valve assembly 16 polypropylene needles Collection rack shelves, legs, clips, & posts 4 plates 24 Position Vacuum Manifold Set-Complete 1 pcs 2.CR Includes: 1 glass chamber 1 cover, gasket, & 24 stopcocks 1 vacuum gauge & valve assembly 24 polypropylene needles Collection rack shelves, legs, clips, & posts 4 plates 1 pcs 10-position Flash Vacuum Manifold 10 Position Flash Vacuum Manifold For your large column applications from 10 to 70g, these introduced processing stations target the large SPE and Flash columns.

44 HPLC Columns 42 HPLC HPLC Columns HPLC Columns HPLC is widely used in chemistry, life science, and pharmaceutical research. Compared with chromatographic supports such as polymeric and graphitic carbon materials, silicabased columns are chosen by most chemist for the selectivity and higher efficiencies. To select the appropriate column for your application, you should choose the phase type, particle size, and column size. Athena Serials Athena HPLC columns are based on high purity spherical silica with low metal residues, providing excellent peak shape for acidic, basic and neutral compounds. The strong mechanical stability and tight quality control guarantee the long lifetime and reproducibility. Seven bonded phases provide broad selectivity for method development. Athena C18-WP Bonded with octadecyl groups Excellent symmetrical peak shape for basic compounds Compatible with 100% aqueous mobile phase High surface area leads to high loadability Stable with mobile phase at ph The special bond technology of Athena C18-WP column enables the use of 100% aqueous mobile phase, which is necessary for some polar analytes. The ph stability allows the mobile phase at ph with long lifetime. The high ph mobile phase can provide good peak symmetry for basic compounds. (A) (B) Specification: Bonded phase Athena C18-WP Particle size (μm) 3 and 5 Pore size (Å) 100 Pore volume (ml/g) 1.1 Endcapped Yes Surface area (m 2 /g) 450 Metals content (ppm) <10 Carbon load 17% ph range Temperature ( C) Aqueous Compatibility Dewetting When working with low organic mobile phases, complete loss of retention can be observed. The phenomenon of dewetting is a shortcoming of conventional reverse phase columns. Dewetting test Some reversed phase columns show durability in 100% aqueous eluent, but when the flow is stopped and restarted, the retention lose. Athena C18-WP column shows superior durability in this test. Retention time and efficiency keeps 90% above after flow stop. Dewetting Test A= Before flow stop B= After flow stop. Column: Athena C18-WP, 4.6 x 150 mm, 5μm Eluent: Methanol : Water (70/30) Flow Rate: 1.0 ml/min Det.: UV 254 nm Temp.: 30 C Sample: 1. Uracil 2. Toluene 3. Naphthalene

45 HPLC Columns Retention to Initial (%) Time (hours) Athena C18-WP Stability at ph 1.5 After the initial injection, the mobile phase was changed to 100% water. After 2 hours, the flow was reduced from 1.0 ml/min to 0.0 ml/min over 10 minutes. The pump consequently stopped for 1 hour. After the stoppage period the flow was restarted again smoothly. Within 10 minutes the flow was increased from 0.0 ml/min to 1.0 ml/min, and then changed to test condition for next injection. ph Stability Common silica packings are limilted to working between ph 2 and ph 7, because low ph (<2) causes hydrolysis of the siloxane bonds destroying bonded layer and high ph (>7) causes silica dissolution. Acidic Resistance at ph 1.5 Column: Athena C18-WP, 4.6 x 150 mm, 5μm Eluent: Acetonitrile : 0.1% TFA (ph 1.5) (50/50) Flow Rate: 1.0 ml/min Det.: UV 254 nm Temp.: 30 C Sample: Toluene 43 Efficiency to Initial (%) Time (hours) Athena C18-WP Stability at ph 11.0 Alkalic Resistance at ph 11.0 Column: Athena C18-WP, 4.6 x 150 mm, 5μm Eluent: Methanol : 0.5% Ammonium hydroxide (ph 11.0) (20/80) Flow Rate: 1.0 ml/min Det.: UV 254 nm Temp.: 30 C Sample: Dipropyl phthalate Athena C18-WP columns can work with eluents from ph 1.5 to 10.

It is orange-pink in color and relatively hard. Chromosorb P generates high column efficiencies for hydrocarbons. Its surface is more adsorptive than the other Chromosorb diatomite grades due to high surface area. Chromsorb W is the most popular grade used for GC work. It is flux-calcined diatomite, is white in color and friable compared to other diatomite grades. It is of utmost importance to take care in handling this material during coating and packing procedures in order to achieve maximum performance. It is relatively nonadsorptive separating polar compounds. Chromosorb G is developed for the GC analysis of polar compounds. It has a low surface area and good handling characteristics. It is non-friable compared to other diatomite packings and will not generate fines during coating or packing procedures. Chromosorb 750 is the latest addition to the diatomite series. It is flux-calcined and has better handling characteristics than Chromosorb W. It is prepared from high purity diatomite crude with exhaustive acid-washing and effective silane treatment.its high degree of chemical inertness makes Chromosorb 750 an ideal packing for bio-medical and pesticide analysis.

Tenax TA can be used as a packing and as a trapping material. Both the EPA and NIOSH specify the use of Tenax in their standard methods. Tenax is particularly useful for the analysis of high boiling compounds such as alcohols, polyethylene glycols, diols, phenols, monoamines and diamines, ethanolamines, aldehydes, ketones, and chlorinated aromatics. Tenax -GR contains 30% graphitized carbon as an integral part of the material. This is not an admixture; the graphitized carbon is co-precipitated with the Tenax polymer. The resulting material gives higher breakthrough volumes for most materials, yet is less water retentive than Tenax -TA. When using this material for packing GC columns, better peak symmetry is observed. Surface area is 24.1m 2 /g. 84 GC Tenax TA Tenax TA Art.

Graphite Ferrules These 99.95% pure graphite ferrules can be used at temperatures up to 450 C without producing bleed or decomposition products. The one-piece design requires no back ferrules. Graphite ferrules are very soft and conform well to the column on compression. These ferrules can be reused as long as care is taken not to overtighten them. Vespel Ferrules Vespel ferrules do not cold flow, are easily reusable, and withstand temperature up to 350 C. At high temperatures, Vespel may adhere to glass or metal. Vespel /Graphite Ferrules Composites of Vespel and graphite combine the advantages of the two materials. They are less likely to adhere to the column than Vespel but are more durable than graphite. Ferrules are easy to reuse and stable at temperatures to 400 C. PTFE Ferrules PTFE ferrules are completely inert and an economical choice. They have an upper temperature limit of 250 C. PTFE ferrules conform well to the shape of the column upon compression and can be reused if handled carefully.

100 Hamilton Syringe Hamilton Syringes Introduction For more than 50 years, HAMILTON has been satisfying customer needs in the field of precision fluid measuring. It all started with syringes. Not commercial, mass-produced medical syringes, but precision measuring instruments. With proper care and handling, HAMILTON syringes will provide unsurpassed performance in precision fluid handling year after year. Point styles 98 Syringe Point styles Syringe terminations pst2 This is the standard point style suitable for all chromatographic applications bevelled, non-coring needle point, recommended for septum penetration. (Only needle gauges from 22 to 26s are ideal for septum penetration.) pst3 This needle has a 90 bevel and is mainly used in HPLC injection valves. It is recommended for sample pipetting and where precision dosing is required (e.g. thin layer chromatography). pst4 This needle is cut at an angle of and has a sharp point for animal injections. pst5 Conical needle with closed end and a side hole. The closed end prevents the needle from being plugged when septa are penetrated (coring). Pst5 needles are available from gauges 10 to 26s. Ideal for penetration of septa, thin-gauged vinyls and plastic without coring. pstas The needles have an 8 cone. They have been designed to penetrate GC Autosampler septa. AS standard needles are available in gauges 26, 26s, 23, 23s, 22, 22s. Other dimensions on request.

109 Selection Guide A VIAL IS A VIAL, OR IS IT? Autosampler vials may seem insignificant when compared to the sophisticated analytical instrumentation most laboratories use, but the incorrect vial, cap or septa can contribute to problems that can decrease productivity and reproducibility. Potential Problems Caused by Using Incorrect Vial/Cap/Septum: Loss of analyte due to evaporation Presence of extra peaks in the chromatogram due to solvent/septum interaction Mechanical damage to autosampler Sample degradation Irreproducible injection volumes What to Consider When Selecting an Autosampler Vial? Autosampler Compatibility Not all autosamplers are alike. Some utilize robotic arms to pick up a sample vial; some use tray rotation while others move the sampling needle to the respective vial coordinates. The dimensions of autosampler vials vary. Most autosamplers are equipped with trays that use 12x32mm vial configurations but some like the Waters Wisp require a 15x45mm configuration. Consult your autosampler s operating manual or manufacturer to determine the vial dimensions required. Sample Volume The amount of sample available for analysis is important in choosing the appropriate vial. If only a limited volume of sample is available, you will have to choose between using an insert for your regular autosampler vial, a microvial or a high recovery vial. Note: Most 12x32 mm autosampler vials hold between 1.5mL to 2.0mL of liquid, depending on where the manufacture measures the vial full. The dimensions for 12x32mm vials are standard between manufacturers but the length of the neck and width/shape of the vial shoulder may vary. 12x32mm microvials have the same outer dimensions but the inside of the vial may be tapered to reduce volume or contain a fused insert. 12x32mm high recovery vials will have an internal conical bottom that allows for maximum sample recovery. 107 Sample Compatibility The analyte and solvent compatibility should be considered in choosing vials and accessories. For example, amber glass is most often used for light sensitive samples while deactivated glass or plastic vials are used for compounds that are sensitive to glass or stick to the glass itself. Volatile samples require closures that reduce the risk of analyte loss due to evaporation. Linear Coefficient of Expansion refers to the fractional change in the length of glass per degree of change in temperature, in short, the ability of the glass to tolerate rapid thermal changes. The lower the coefficient of expansion the better the glass can handle temperature change without fracturing. Classifications for laboratory glass based on its resistance to attack from water were established by the United States Pharmacopoeia, USP. USP Type 1, Class A, 33 Borosilicate Glass is the most inert and chemically resistant glass widely used in laboratories especially for chromatography applications. Type I glass is composed primarily of silicone and oxygen, with trace amounts of boron and sodium. It has the lowest leaching characteristics and a linear coefficient of expansion of 33. USP Type 1, Class B, 51 Borosilicate Glass which is composed of silicone and oxygen, trace amounts of boron, sodium and other element is more alkaline than Class A glass but still adequate for laboratory use. All amber borosilicate glass is made of Class B unless otherwise specified and has an expansion coefficient of 51. Silanized or deactivated glass is borosilicate glass that has undergone further deactivation by treating the surface of the glass with an organosilane. The surface Sample Vials

110 Selection Guide becomes more hydrophobic and inert making the vial suitable for use with ph sensitive compounds, trace analyses and applications requiring long term sample storage. USP Types II, III and NP glass are manufactured from soda lime which has less chemical resistance than borosilicate. Polypropylene is a rigid and translucent material, which also comes in a variety of colours and has good chemical resistance for short term storage of most common laboratory chemicals. Resistance decreases over time when using aromatic and halogenated hydrocarbons. Polypropylene vials are often used for ion chromatography because of the extremely low metal content and excellent cleanability with dilute acid followed by deionized water rinse. Polypropylene vials limit the exposure to hazardous materials since they can be incinerated while sealed. Polymethylpentene (TPX) is a rigid transparent material, which has a relatively high melting point with a temperature range of C. TPX vials can be used as alternative to opaque polypropylene vials because they provide maximum clarity. Their chemical resistance is similar to that of polypropylene vials. TPX vials should be used for applications where visual clarity is required or repetitive exposure to higher temperatures such as autoclaving. TPX vials tend to be more brittle at room temperature. 108 Sample Vials Type of Vial Finish and Closures Autosampler vials are available in a variety of neck finishes and opening diameters. Large mouth or wide ID vials have approximately a 40% wider mouth opening than standard opening vials. The large opening reduces the risk of bent autosampler needles during sampling. Screw thread vials and caps provide low evaporation, reusability, less hand injury during manipulation than crimp seals and require no special tools. All screw threads vials and caps are differentiated by their thread finish as defined by the Glass Packaging Institute, GPI. For screw thread vials, a two part number is assigned. For example, neck finish represents a vial with a diameter of 8 mm across the outside of the threads and a thread style of 425. Screw thread vials and caps are more expensive than crimp seals. Caps for screw thread vials are available with either an open hole for autosampler use and standard addition or with a solid top for sample storage. One piece polypropylene cap and membrane are also available. These pierceable screw thread caps are designed for one time use and reduce sample preparation time as there is no cap and seal to assemble. Crimp top vials require lacquered aluminum crimp seals which are relatively inexpensive and, when properly assembled, provide the best seal for long term storage. Crimp seals are not reusuable. A crimping tool is required to seal caps and a decrimper or decapper is required to remove the seals. Several types of hand crimpers are available including the adjustable precision crimpers that Chromatographic Specialties offers. Adjustable hand crimpers feature an adjustable stop on the handle to provide consistent seal tightness every time. Adjusting the hex screw inside the steel crimper jaws will also alter the amount of crimp. Achieving a good crimp is crucial because overcrimping can cause septum coring, bent needles and create a larger hole in the Teflon septum layer than a properly crimped seal. Undercrimping can result in loose seals and sample evaporation. Snap seal vials are less prone to breakage during decapping because more glass is used in the neck of the vial. The snap seal neck finish is compatible with either crimp and/or snap seals and no special tools are required to remove the cap. These vials are recommended for short term sample storage and non-volatile samples because the seal is not as secure as a crimp or screw thread seal. Shell vials are an economical alternative to screw thread vials for Waters' HPLC autosamplers or any other autosampler that doesn t use a robotic arm to move the vials. Most shell vials are sold with a polyethylene cap that has a starburst design for easy needle penetration.
