Review Paper for Sample Separation and Preparation for Gas Chromatography

Sample directly introduced into the injector port of the Gas Chromatographer (GC) is subjected to the programmed thermal environment in response to which the adsorption and elution of the compounds takes place internally of the capillary column and physical separation of individual compound takes place. Since the mobile phase is gas, a limitation on the type of sample introduced is abided. If the sample is conditioned to proper needs and a required amount is inserted, then better resolution of peaks as a result is encountered. This paper showcases the technologies and novel approaches towards the sample separation and preparation to make the GC instrument better in its performance.
