An Examination of GC Columns and their Effect on Volatile Organic Compounds


The efficiency of a Gas Chromatograph depends significantly on the type of column that is installed in it. In order to properly separate every compound in a mixture from each other, the optimum column must be used. In this study we will be using Method 8260D of the United States Environmental Protection Agency (USEPA) in order to compare two 624 phase columns with dimensions 30m x 0.25mm x 1.4μm and 20m x 0.18mm x 1.0μm.
