Figure 1: A simplified diagram of a gas chromatograph showing: (1) carrier gas, (2) autosampler, (3) inlet, (4) analytical column, (5) detector and (6) PC.Credit: Anthias Consulting. After injection into the GC inlet, the chemical components of the sample mixture are first vaporized, if they aren't already in the gas phase. Electron ionization - Wikipedia Electron ionization was first described in 1918 by Canadian-American Physicist Arthur J. Dempster in the article of "A new method of positive ray analysis." It was the first modern mass spectrometer and used positive rays to determine the ratio of the mass to charge of various constituents. In this method, the ion source used an electron beam directed at a solid surface. Capillary Gas Chromatography - an overview | ScienceDirect ... Photograph and block diagram of gas chromatograph. (Hewlett Packard, HP 6890.) GC has steadily progressed into capillary GC. The determination accuracy of the split injection of a sample is improved by using an autosampler injecting the sample for a period as short as 0.1 seconds. The loss of a component in the sample can be decreased and ... PDF Basics & Fundamentals - Gas Chromatography Basics & Fundamentals: Gas Chromatography. Introduction . Gas chromatography (GC) is an analytical methodology, which was devised by Nobel Laureate, Martin, et al. in 1952. More than 60 years after the award, GC systems are widely commercialized and used in various industries, capable of both of quantitation and qualifcation.
