Gas chromatography is an analytical method used to separate and analyze compounds that can vaporize without decomposition. This technique is essential in identifying the composition of gases and volatile liquids, playing a crucial role in various scientific fields, including geochemistry, where it helps to analyze isotopic ratios and trace elements. Gas chromatography can help reveal insights about processes like Rayleigh fractionation, carbon isotopes in paleoclimatology, biological processes, groundwater contamination, and food authentication.
