Gas Chromatography

Gas chromatography is vital topetrochemical analysis where its roles range fromon-line monitoring of process streams and characterization of feeds, intermediates, and productsin refinery operations, and to providing analytical datato meet environmental regulations.

Petroleum Palace Group provides GC analysis for a wide range of applications in oil and gas industry. Below mentioned table listssome ofthe major GC methods approved by the AmericanSociety for Testing and Materials (ASTM), reflecting the wide variety of GC applications for petroleum-related materials.

In addition to the oil-related products Petroleum Palace Group provide GC analysis for a wide range of complex mixtures of different molecules, to determine 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, allowing the analyst to identify both the types of molecular species present and their concentrations.
