Over the past 50 years, Gas Chromatography has emerged as a critical analytical tool across various sectors of the petroleum industry. It plays a significant role in crude oil exploration, product refining, and research on new petrochemical compounds. Gas Chromatography (GC) is widely recognized as one of the fundamental techniques in modern analytical chemistry. Its primary function is to separate complex mixtures of molecules based on their physical properties, such as polarity and boiling point. This makes it particularly useful for analyzing gas and liquid samples containing numerous molecules, as seen in crude oil and its derivatives. With GC, analysts can identify the molecular species present in a sample and determine their respective concentrations.
