Sometimes, however, you need to use a column that has nonstandard dimensions, tests, or other special criteria. Because Varian performs the entire production process in-house, we can address almost any requirement and supply almost any special column you request. For instance, some of the custom columns that Varian can deliver include: Columns in a variety of lengths and film thicknesses EZ-Guard columns Columns with a retention gap or transfer line tested for leaks Analytical columns coupled and tested for leaks Columns custom tested with a specific test mixture and test conditions Don t let a special requirement prevent you from following up a line of critical research. Please contact your local Varian sales office with any questions regarding custom-made columns and price quotations. Columns on a Varian 5-in. Cage Most GC columns are also available on a 5-in. cage. The 5-in. cage can be attached to Varian s standard 7-in. cage with EZ-GRIP. This lets you easily and conveniently install together one 7-in. and one 5-in. column with EZ-GRIP, saving valuable oven space. The Varian 5-in. cage will also fit the HP6850 GCs. Varian capillary columns on 5-in. cages can be ordered via standard part numbers by adding the suffix i5 to the end of the regular 7-in. part number. For example, the 5-in. version of CP8944 will be CP8944i5. The price of the column on a 5-in. cage is the same as the price for the same column on a standard 7-in. cage. Note: Our columns on 7-in. cages are delivered with EZ-GRIP, but our columns on the smaller 5-in. cages are not.

4 Varian GC Columns 195 GC Column Specifications Optimized Performance Through Controlled and Tight Specifications Varian GC columns are produced following exacting ISO 9001 certified procedures. This process guarantees that all Varian GC columns are manufactured using a systematic and controlled process. Varian draws its own fused silica tubing in order to control quality. In addition, Varian synthesizes the stationary phases that we use for our capillary columns, which enables us to produce capillary columns to the tightest specifications. Optimal Separation The efficiency of a column, N/M (theoretical plates per meter), is a measure of a column s separation power. Columns with higher plate numbers per meter have a high separation power. This means they provide greater resolution of two peaks. Guaranteed Column-to-Column Reproducibility The retention Index, RI, is the measure of column selectivity, and indicates the elution order of compounds. Columns with a small RI variation between them will produce the same elution order. By setting tight specifications on the retention index, we make sure the column-to-column reproducibility is as high as possible, giving you the guarantee that your Varian column works exactly the same way each and every time. Reproducible Retention Times The phase ratio, Beta, is a measure of the component s retention time, and depends on the phase film thickness. Columns with a small variation in Beta will have a high column-to-column retention time reproducibility. Varian columns are manufactured to ensure high column-to-column retention time reproducibility. Low Bleed Provides Increased Sensitivity Column bleed is the formation of volatile products caused by the degradation of the stationary phase. Column bleed, measured in pa, causes baseline shifts and high noise levels that reduce peak measurement accuracy and precision. Bleed is minimized on Varian columns, as we draw our own fused silica tubing and use in-house manufactured stationary phases. Low bleed delivers reduced noise level and increased sensitivity. In addition, low bleed columns have a longer column life, and reduce the contamination of detection devices, which means detectors require less maintenance with Varian columns. More Accurate Peak Identification The inertness of a column, measured by peak asymmetry, As, directly influences the elution and recovery of polar (active) compounds. The closer the As value is to 1.0, the more symmetrical the peak shape (less tailing), and therefore the more accurately the peak can be quantified, particularly with acid-base compounds. Inert columns deliver far more reliable results, and Varian columns deliver those results. Operating Temperature Ranges for Varian GC Columns Varian specifies the maximum and minimum operating temperatures for each Varian GC column. The Maximum Allowable Operating Temperature of a stationary phase, (MAOT), is the maximum recommended temperature at which it can be operated without a change in chromatographic characteristics. For each Varian phase and column dimension, the values are listed with the ordering information, and on the test report that is supplied with each column. For temperature-programmed analysis, the MAOT is generally 20 to 25 C higher than that for isothermal operation. For each Varian stationary phase and column, two maximum operating temperatures are specified. The first is the maximum isothermal operating temperature, which Varian has defined in two different ways. One is applied to FactorFour and other low bleed columns, and the other is applied to all other available stationary phases. Maximum Isothermal Temperature for Factorfour and Other Low Bleed Phases: The maximum isothermal temperature is the temperature at which the column bleed does not exceed a certain specified level. Varian has set these bleed levels such that optimal analytical results can be obtained near the specified upper temperature limit of the column. As a result, exceeding this specified column upper temperature limit will not always mean that the liquid phase is destroyed. The column will of course exhibit higher bleed levels than specified by Varian. As rule of thumb, the bleed level doubles with every 12 C rise in temperature. Bleed levels will return to their previous levels once the oven temperature is returned to lower settings. Maximum Isothermal Operating Temperature for All Other Varian Stationary Phases: The maximum isothermal temperature is the temperature at which after a period of six months continuous use the amount of phase is reduced to 50% of the original layer. The use of higher temperatures than indicated will lead to reduced column lifetime and possible changes in elution order because of partial thermal degradation. Maximum Temperature Programmed Operating Temperature The other specified maximum operating temperature is the temperature programmed operating temperature. The definition for maximum programmable temperature differs only in the time span: a 50% reduction of phase in 200 hours. Usually this results in a maximum programmable temperature of 20 to 25 C higher than the maximum isothermal temperature. Minimum Operating Temperature The minimum operating temperature is the lowest usable temperature where the stationary phase is liquid. Operating the stationary phase below its minimum temperature will not destroy the stationary phase, but poor peak shape and resolution will result.

16 GC System Background Sources 207 GC System Background System Background and Noise Generation How to identify and reduce the sources of rising baselines in GC analysis When a high background is observed, the GC column is often targeted as the cause, and a high-temperature column bakeout or column replacement is used to fix the problem. However, in gas chromatography, the background is frequently generated by a different source. In order to measure accurately at trace levels, the entire GC system needs to be optimized and background (noise) must be minimized. Background in any GC-MS system is the sum of contributions that begin with the carrier gas, tubing, injection device, and column, ending with the detector, where several sources of high background also exist. Minimizing system background provides several advantages: Injector and Septum The majority of injection systems are based on split/splitless injection, and sample introduction is done with a syringe via a septum. The septum is probably the largest source of high background. Since the septum is made of 100% polydimethylsiloxane (the same material that is used to manufacture stationary phases), any degradation product will appear to be similar to a stationary phase bleed product. The use of round-bottom needles and high-quality septa can reduce the generation and release of septum particles. Replacing the septa and insert on a regular basis will also help. Lower detection limits and more accurate data Reduced contamination of the detection system Better spectra in mass spectroscopy Faster start-up times Impurities in Carrier Gas and Gas Lines Any contaminant in the carrier gas will end up in the GC. The purest carrier gas can be used, but if a cylinder is changed, a gas line is opened, or an in-line filter is replaced, there will a considerable amount of air (and impurities) introduced into the gas system. To reduce this risk, it is recommended to use a filter system with an indicator, which is placed as close as possible to the GC carrier gas inlet. Our Gas Clean filters are ideal for this purpose. Extension of gas lines in the laboratory must be done with clean tubing. Figure 2. These peaks show typical phthalate masses. Phthalates are used as Softeners in septa. Injector Liners Glass wool liners are excellent for increasing evaporation and ensuring reproducible injections, but can cause ghost peaks and bleed by trapping of septa particles and bleed products, or the release of deactivation of glass wool. Glass wool works fine if the effect of septa bleed and particles is reduced. Using a different insert without glass wool can provide an alternate solution. Figure 1 shows the difference in bleed levels with and without a carrier gas filter when running a temperature program (50 C to 350 C, 20 C/min). When no filter is used, an extreme rise in the bleed profile is clearly visible due to moisture in the carrier gas. By using filters placed as close as possible to the GC carrier gas inlet, a normal bleed profile is achieved with the removal of all moisture in the carrier gas. Blank runs GC Columns The Sample Often, the background and ghost peaks that are assumed to be background are a result of contamination from the sample. Even with pure solvents, this background is evident. Contamination can occur in the sample when it is delivered in a vial. The vial is often sealed with a cap on a rubber/silicon seal. Unfortunately, the cap often releases softeners or siloxanes into the sample. Typically, when a sample is stored in a vial and analyzed after 4-8 weeks, many extra peaks will be observed. Solvent contact with the cap should therefore be minimized. See All of Our Products, and Shop Online at

17 208 GC System Background Sources Contamination from the Outside Columns can be easily contaminated during installation by transfer of skin oils or hand creams, etc. Because many moisturizers contain siloxane, the column exterior can become contaminated. This is particularly important when using MS detection, since there is no gas flow along the outside of the fused silica when installed as a transfer line in an MS system. The contaminants can drift toward the ionization chamber, contributing to long stabilization times. Cleaning the end of the fused silica with tissue and methanol before it is inserted in the transfer line is always recommended. This also shortens stabilization times with the detection system. Oxygen and Moisture Contamination Introduction of air in the GC system via leaks The introduction of moisture and oxygen can cause high background, tailing, and shifting of retention times. This can happen via leaks and is introduced via the gas supply, coupling, septum, and connections. Leak detection is thus important and is recommended to be done before conditioning the column by handheld leak detectors, which can locate leaks at difficult spots such as the septum. Did you know that EZ-Guard columns include an integrated retention gap for leak-free operation? Introduction of air in the GC system via air exposure Transfer lines in MS are potential sources of background contamination. When performing column or injector maintenance, to save time the operator may leave the vacuum source on while sustaining a high temperature on the transfer line. A large volume of air (containing moisture and oxygen) can pass through the hot transfer line, causing a great deal of activation and degradation of the stationary phase in the line. The subsequent analysis can exhibit higher background and less peak abundance due to adsorption. The Stationary Phase Each stationary phase will start to decompose when heated at elevated temperatures. The stationary phase will form degradation. The absolute bleed level depends on the nature of the stationary phase, the temperature and the amount of phase present in the column. The formation of degradation products can be reduced by stabilization of the stationary phase, leading to lower background. The stationary phase stabilization technology and the optimization of the fused silica surface all contribute to the low bleed specifications of Varian s FactorFour columns. For optimal results, condition the columns 20 C above the final analysis temperature or at the maximum temperature of the column. For reducing column bleed without the risk of damage from oxygen in the carrier gas, longer conditioning times at lower temperatures may be more effective.

18 Varian FactorFour GC Columns 209 Varian FactorFour Capillary Columns Highly Inert Capillary Columns with the Lowest Bleed Specifications - Guaranteed Lower detection limits Improved inertness Longer column lifetime Reduced detector contamination Enhanced instrument performance Varian FactorFour capillary columns have quickly become the industry standard for high performance GC and GC/MS analysis. Using optimized manufacturing technologies and a comprehensive set of QC specifications, FactorFour columns deliver the new standard for ultralow bleed column performance. The Varian FactorFour capillary column line has been expanded to become a complete, comprehensive family of stationary phases, suitable for industrial, toxicology, petrochemical, and trace environmental applications. The Basis for FactorFour Superiority Varian controls the entire in-house manufacturing process to supply you with FactorFour columns that have a reduced bleed specification by up to a factor of four. This bleed reduction significantly improves column performance in many ways. The process of bleed formation depends on the integrity of the fused silica capillary surface, polymer coating and conditioning technology. First, to ensure absolute integrity, Varian draws its own capillary tubing specifically for the production of capillary columns - a rare attribute. By controlling the conditions during fused silica drawing, the surface can be optimized for deactivation and low bleed. Second, in-house synthesis of the stationary phases has led to the development of new, proprietary technologies that reduce the fundamental breakdown processes that causes column bleed. Third, the conditioning of FactorFour columns is done at optimized temperatures under high purity gas that s purified using the Varian Gas Clean Filter system. Finally, all FactorFour columns are manufactured under close supervision to exacting specifications and are rigorously tested, so you re guaranteed that every FactorFour column meets the Varian FactorFour performance specifications. Ultralow Bleed All FactorFour columns deliver extremely low bleed rates. In fact, their bleed specifications are up to four times lower than competitive products (Figure 1). Figure 2. Figure 1. GC Columns The ultralow bleed achievable from FactorFour columns provide many benefits: Accurate peak identification enables you to achieve more reliable results Superior response for traces delivers better quantification Enhanced detector performance increases productivity and reduces your costs Faster stabilization ensures longer instrument uptime and increased productivity Longer column lifetime lowers the cost per analysis (Figure 2).

19 210 Varian FactorFour GC Columns Superior Inertness Besides the ultralow bleed specifications, FactorFour columns are highly inert, thereby providing accurate peak identification and more reliable analysis. See Figure 3 for an inertness comparison of the VF-35ms and competitor X. Figure 3. FactorFour VF-1ms Low bleed 100% dimethylpolysiloxane phase Guaranteed lowest bleed specification Wide variety of applications VF-1ms VF-1ms columns deliver all the benefits of FactorFour technology to the analysis of a wide variety of components. The nonpolar VF-1ms phase is ideal for analyzing nonpolar components. Even better, the high quality fused silica surface and deactivation technology make the column also applicable for a wide variety of semi-polar and even polar components - providing you with an extremely flexible solution. The bleed specification is 1 pa (30m, 0.25 mm, 0.25 µm) at 325ºC the lowest in the industry. Optimal Performance with Sensitive Detectors FactorFour ultralow background noise enables optimal performance of sensitive and selective detection systems. FactorFour applications are not limited to MS detectors. Virtually every type of detector will operate with greater stability due to the low-bleed characteristics of FactorFour columns. EZ-Guard EZ-Guard columns combine a low-bleed FactorFour column with a 5 or 10m integrated guard column. The inspired design eliminates guard-tocolumn coupling and the possibility of leaks. Also, EZ-Guard columns feature an uncoated, deactivated outlet section that acts as an integrated transferline for faster stabilization in MS and other detection systems. See page 222 to read more about the new 100% leak-free protection of analytical FactorFour columns. Specifications that Guarantee Quality Varian is committed to the highest product quality specificatoins. Each column is tested and shipped with its original certificate of analysis. It s your guarantee that every Varian GC column is of the highest quality and will work consistently each and every time. In addition, one of the many specifications for a FactorFour column is its retention index. The retention index determines compound elution order, as measured to set specifications. The smaller the deviation of the retention index, the higher the reproducibility of peak elution order. The narrow FactorFour retention index tolerance guarantee the highest column-tocolumn reproducibility. EZ-GRIP As with all Varian capillary columns, FactorFour columns are shipped on EZ-GRIP cages for ease-of-use during installation, operation, and coupling. See EZ-Grip in use on page 193. Typical Analyses: Alcohols, aromatic hydrocarbons, esters, flavors and aromas, free fatty acids, glycols, halogenated hydrocarbons, hydrocarbons, ketones, organic acids, oxygenates, PAHs, pesticides, polymers, steroids, solvents, sulfur compounds Similar Phases: DB-1, DB-1MS, HP-1, HP-1ms, Rtx-1, Rtx-1ms, SPB-1, Equity-1, Ultra-1, BPX-1, Solgel-1MS, 007-1, AT-1, Optima-1, ZB-1, CP-Sil 5 CB, CP-Sil 5 CB Low Bleed/MS NEW! 0.53 mm columns 0.53 mm VF-1ms columns are ideally suited for valve or on-column injection techniques. High flow rates are possible with their use, enabling fast analysis and low elution temperatures. NEW! EZ-Guard Columns The VF-1ms column is now available with a film thickness of >1.0µm. Thicker films allow a better separation of more volatile compounds. The 0.32 mm thick film columns have a unique uncoated section at the outlet. A shorter stabilization time will be obtained when used with any type of detector. The absence of stationary phase in the last part of the column will significantly reduce background. Therefore, the impact of water, oxygen and other polar/aggressive components that move through this part of the column at high temperature will be greatly reduced - offering improved analysis for volatile samples. Combine FactorFour low bleed GC columns with the quality gas delivery of Varian s Gas Clean Filter and you create the best combination for optimal GC and GC/MS performance.

31 222 Varian FactorFour GC Columns EZ-Guard No column coupling means no risk of leakage Easy and fast to install and operate Integrated transferline allows for faster detector stabilization Eliminates dead volume, thermal capacity, and fragility issues Faster Stabilization Each EZ-Guard column also features a unique uncoated and deactivated outlet section, approximately 100 cm in length, which acts as an integrated transfer line. This results in a shorter stabilization time with all types of detectors. The absence of a stationary phase in the last part of the column will significantly reduce background noise. The impact of water, oxygen or other polar or aggressive components that move through the end of the column at high temperature will also be greatly reduced. The Varian EZ-Guard column is based on the FactorFour technology, and offers the lowest bleed specifications available. Column bleeding is minimized to deliver all the benefits of low bleed. Operation NEW! A special tab clearly distinguishes the EZ-Guard guard column section from the analytical column. NEW! Guard columns (or retention gaps) are often added to the front of the analytical column to protect against contamination, or to act as a band-focusing device for liquid samples introduced by on-column and splitless injection techniques. For these applications, the new Varian EZ-Guard column combines a FactorFour column with a built-in guard column. When resolution or response in the chromatogram diminishes, a coil is removed from the EZ-Guard column so that peak shapes will improve. By removing a coil, the column length is shortened and peaks will elute somewhat faster. For best results, check the integration time windows of your data system. Similar products: Integra-Guard columns (Restek), Dura Guard columns (Agilent) EZ-Guard columns are available with the VF-1ms, VF-5ms and VF-Xms phases. Contact your local Varian office or distributor if you want to benefit from EZ-Guard with other FactorFour phases. The first 5- or 10-meter section of the EZ-Guard column (guard length depends on the column you select) is not coated with stationary phase, but it has been deactivated. The lack of a column connection between the guard and analytical sections results in a 100% leak-free column. As a result, former problems with installation, peak shape and leaks just don t occur!

45 236 Varian PLOT GC Columns Varian PLOT GC Columns Porous Layer Open Tubular capillary (PLOT) columns are ideal for separating gases and volatile compounds. The stationary phase of PLOT columns is based on an adsorbent or a porous polymer. This allows users to experience the benefits of high-resolution capillary gas chromatography when analyzing a wide range of gases and volatiles. Varian s PLOT columns deliver superior mechanical and temperature stability, and allow for increasingly fast methods. Varian has been the industry leader in PLOT technology since we introduced the first PLOT column in Today Varian not only continues to offer the widest range of PLOT columns, but now also delivers the latest generation of highly stable bonded PLOT columns with improved reliability in the analysis of volatile solvents and hydrocarbons. NEW! The Varian Select Al2O3 MAPD The Varian Select Al2O3 MAPD is an aluminum PLOT column optimized for Methyl Acetylene and Propadiene Response for unsurpassed analysis of trace reactive hydrocarbons in the C1-C10 range. See page 248 for more detailed information. Did you know that pressure pulses can damage PLOT columns?

46 Varian PLOT GC Columns 237 Bonded PLOT Columns The new generation of adsorption materials deliver the highest resolution and shortest analysis times When developing bonded PLOT columns, Varian created a unique column coating process that grows the porous polymer layer in-situ within the column. As a result, the Varian bonded PLOT columns show superior stability, zero particle loss and low bleed when compared to the older manufacturing process of coating the inside of the column with discrete particles. These outstanding capabilities in turn lead to improved methods, eliminate the risk of particle loss, and the need for particle traps. Higher temperature specifications together with the improved separation of volatile compounds make bonded PLOT columns a better choice than conventional general-purpose columns for many methods in the chemical, petrochemical, and pharmaceutical industries. Varian bonds the porous polymer to the column so there are no loose particles to cause detector spiking or valve columns. This makes PoraBOND columns ideal for use with pressure programs, GC/MS applications, and valve switching. Due to the bonding of the PoraBOND columns, they withstand repeated water injections.

In fact, UltiMetal columns are virtually unbreakable. KCl or Na2SO4 Deactivation The aluminum oxide PLOT columns are deactivated using very small salt crystals, providing a reproducible and stable deactivation up to 200ºC. Depending on the type of deactivation salt, the CP-Al2O3 column will show different selectivities. KCl salt deactivation results in a relatively nonpolar Al2O3 surface, while Na2SO4 deactivation results in a polar surface where unsaturated compounds like ethylene and acetylene (ethyne) and methyl acetylene (propyne) are retained longer.

74 Varian Packed GC Columns 265 Packed GC Columns Varian has over 25 years experience developing and manufacturing industry-leading GC packed chromatography. Varian GC packed columns are manufactured in-house under ISO-certified procedures to ensure the best and most reproducible GC packed columns. Varian supplies a wide range of GC packed columns, packing and support materials. Custom-Made Packed Columns Custom-made packed columns may be constructed of glass, stainless steel, or Teflon and are packed with up-to-date supports and phases. All columns are deactivated with dimethyl dichlorosilane (DMCS) and plugged at both ends with DMCS-treated glass wool. Stainless steel columns are available in 1/8 and 1/4 outside diameters (OD) and lengths of up to 10m. The columns are supplied with brass fittings. Stainless steel and other specific fittings are also available. Glass columns are available in 1/8 or 1/4 (OD) and lengths of up to 10 m. The inside diameter of 1/8 OD columns is 2 mm and 2, 3 or 4 mm in the 1/4 OD columns. Brass nuts and graphite ferrules are included. Teflon columns are available in 1/8 and 1/4 (OD), and are supplied with brass nuts and teflon ferrules except for Shimadzu models. Custom-Coated Packings Varian can supply any coated packing for your packed column application need; even mixed liquid phases are possible. Custom-made packing materials are freshly prepared according to your specifications. The packings can be pretested, in which case they will be supplied with a test chromatogram. They are then shipped in glass bottles filled with an inert gas to prevent contamination and oxidation. When ordering custom-made packings, please specify as follows: 1. Part Number CP quantity of packing in (minimum of 10 grams) 3. loading of liquid phase(s) 4. liquid phase(s) 5. support 6. mesh size 7. pretested, if desired Example of packing description Part Number CP g 10% SE-52/ Chromosorb W AW-DCMCS mesh Supports When ordering supports, please specify as follows: 1. part number CP quantity of packing (minimum of 10 grams) 3. support 4. mesh size GC Columns Example of support description Part Number CP g Chromosorb mesh See page 266 for an overview of the available stationary phases.
