Varian GC Columns 193GC Capillary ColumnsWhy Buy Varian GC Columns? High quality Individually tested Application specific solutions Published, guaranteed specifications EZ-GRIP provides ease-of-use Leading-edge technology
Varian GC capillary columns stand for quality and the latest innovation. Varian is uniquely positioned to deliver the highest quality capillary columns with the most demanding quality assurance specifications in the industry. Thats because we control the entire manufacturing process in-house from the production of the fused silica tubing and stationary phase, all the way through column manufacturing and quality assurance, design and technology. Varian columns are the most reproducible on the market, which is reflected in our published specifications. A final quality touch: each Varian capillary column is individually tested.
Varian GC Capillary Column ProgramVarian offers the most complete capillary column selection available on the market today, and provides a wide variety of ultra-low bleed and general purpose columns as well as specialized Porous Layer Open Tubular capillary (PLOT) columns for gases and volatile compounds. Also available are Select columns, application specific columns for environmental, food and fragrance, chemical, and chiral analyses. Youll find that theres a Varian capillary column to meet your need, with a range of features suited to optimize your specific application. In addition, each Varian capillary column is supplied with EZ-GRIP, the unique system that makes installation, coupling, and operation of your capillary column easier. For a complete overview of Varians GC column program, phase composition and application area, see page 196.
Varians Unique EZ-GRIPSupplied with Each Standard GC Capillary Column Easier precolumn/retention gap and dual-column installation Secure, error-free connections for optimum column performance Saves installation time with complete, unified column system
1. Special tabs on EZ-GRIP secure up to 15 meters of precolumn and retention gap tubing. 2. Each EZ-GRIP includes two brackets to firmly attach single ferrule column connectors to a precolumn, transfer-line, or second analytical column. 3. EZ-GRIP firmly attaches a second analytical column on a 5-in. cage to create rugged and easy-to-handle dual column configurations. See page 194 for more information on Varians GC columns on 5-in. cage. 4. EZ-GRIP tabs conveniently hold the column inlet and outlet ends during storage and installation. Inlet and outlet ends are clearly marked on the EZ-GRIP bar, eliminating accidental reverse-direction reinstallation and the extra time needed to reinstall or bake out/back flush the column. 5. The unique column scale is in the ideal location to help you accurately and quickly measure the correct column length to insert into the injector and detector. Also, standard Varian 3800 GC insertion lengths are pre-marked to save you from time and eliminate errors.

Varian GC ColumnsVarians Application Specific Columns: Select Columns
The Latest GC Capillary Column InnovationsVarians Ultra-Low Bleed FactorFour ColumnsWith the introduction of FactorFour Varian has set a new standard for capillary column performance. The comprehensive family of stationary phases with up to four-fold lower bleed specification than comparable competitive products available today has been expanded with both new dimensions and new phases.
Varian Select Silanes
The Varian Select Silanes fused silica capillary column is a stabilized trifluoropropyl-methyl polysiloxane phase optimized for silanes determination. The thick film of the Varian Select Silane results in a high capacity and retention for highly volatile silanes, which also enables you to perform composition as well as impurity analysis down to ppm levels.
Phase composition: A mid polar arylene stabilized equivalent of 50% phenyl, 50% dimethylpolysiloxane low bleed stationary phase. Ideal applications: antidepressants, herbicides and pesticides.
Varian Select Al2O3 MAPD
The Varian Select Al2O3 MAPD is an aluminum PLOT column optimized for Methyl Acetylene and Propadiene (MAPD). Response for unsurpassed analysis of trace reactive hydrocarbons in the C1-C10 range.
Phase composition: A mid polar arylene stabilized equivalent of 35% phenyl, 65% methyl dimethylpolysiloxane low bleed stationary phase. Ideal applications: aromatic compounds, pesticides and herbicides, sterols and other substituted aromatic compounds in trace environmental and analytical analysis.
Varian Custom GC ColumnsVarian offers a wide range of stationary phases in several dimensions. 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 Dont 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.
Phase composition: A trifluoropropyl-methyl low bleed stationary phase. Ideal applications: high dipole (electron rich) compounds like ketones, aldehydes, nitro-, chloro-, bromo-, fluorocontaining compounds, substituted aromatic compounds, unsaturated compounds, silanes and CFCs.
0.53 mm columns are ideally suited for specific injection techniques such as valve, on-column, and direct injection. High flow rates are possible, allowing fast analysis and low elution temperatures.

Columns on a Varian 5-in. CageMost GC columns are also available on a 5-in. cage. The 5-in. cage can be attached to Varians 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.
The Varian EZ-Guard column combines a FactorFour column with a built-in Varian guard column (retention gap). Theres no coupling so no leaks! The EZ-Guard columns also have a unique uncoated section at the column outlet, which acts as an integrated transferline. When used with any type of detector, a shorter stabilization time will be obtained.
Varian GC Columns 195GC Column SpecificationsOptimized Performance Through Controlled and Tight SpecificationsVarian 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.
