Gas Chromatography (GC) columns are at the heart of the gas chromatograph and responsible for the separation process. GC is one of the most important and critical tools in analytical chemistry, because of its effectiveness, sensitivity and ease-of-use. GC columns contain a stationary phase, typically a polymeric material. It is through the interaction between the analytes and this stationary phase within the column that separation of the analyte into their molecular components can occur. 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. When resolution or response in a chromatogram diminishes, remove a coil from the 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.
