The material to be tested (drilling fluid, cuttings, etc.) is placed in a headspace analysis vial and heated. The hydrocarbons C₁–C₉ released during heating automatically enter a gas chromatograph, where they are separated on a capillary column. The chromatography workstation performs data acquisition and automated processing, calculating peak areas for more than 100 components, allowing the content of each component to be determined in the C₁–C₉ range. Using specialized software, a report is generated on the group hydrocarbon composition with distribution by the number of carbon atoms: alkanes, alkenes, cycloalkanes, aromatic hydrocarbons. The data obtained are important for assessing the quality of crude oil.
