Varian Gas Chromatograph - Model 3400

In gas chromatography (GC), an inert carrier gas serves as the mobile phase that elutes the components of a sample mixture from a column containing an immobilized stationary phase. GC began in 1941 and since that time has become one of the most widely used analytical techniques primarily due to the wide variety of columns that are available for gas chromatographs. The Varian 3400 gas chromatograph located in the Multi-User Analytical laboratory has a packed column and a capillary column set-up with split/splitless injector on the capillary column. The packed column system has a flame ionization detector and the capillary column set-up has an electron capture detector. An 8200 autosampler (48 sample capacity) is associated with the system to allow for analysis of samples overnight or during off-time. The system is controlled through a personal computer equipped with Varian Star Workstation software and a LaserJet printer. The software allows for the reintegration and reprinting of previously run samples and well as the export of chromatograms into Word Processing programs.
