Gas Chromatography and Troubleshooting for the Oil & Gas Industry




Introduction:

In the past 50 years, Gas Chromatography has become an important analytical tool in virtually every phase of the petroleum industry, from the exploration of crude oil and refining of finished products to research on new petrochemicals. Gas Chromatography (GC) is one of the most widely used techniques in modern analytical chemistry and its basic form, is used to separate complex mixtures of different molecules based on their physical properties, such as polarity and boiling point. It is an ideal tool to analyze gas and liquid samples containing many hundreds or even thousands of different molecules, as in the case of crude oil or its products. The technique allows the analyst to identify both the types of molecular species present and their concentrations.

This training course introduces the fundamental theory of Gas Chromatography along with the operation, maintenance, and troubleshooting, from sample introduction through to data analysis. Instrument components are described and presented, along with their underlying theories as they apply to guide best practices and effective method optimization and troubleshooting.

Because of the variety and complexity of sample types, petroleum chemists use a broad spectrum of gas chromatographic methods. You will learn about current best practices in terms of system configuration choices and initial method conditions
