Description

In the Gas Chromatography Lab whole oil analyzes are performed with special attention to saturated hydrocarbons, highly volatile organic compounds, and lipid fractions (e.g. fatty acids, alcohols, sterols).

Instruments

Gas chromatography - specifically gas-liquid chromatography - involves a sample being vapourised and injected onto the head of the chromatographic column. The sample is transported through the column by the flow of inert, gaseous mobile phase. The column itself contains a liquid stationary phase which is adsorbed onto the surface of an inert solid.

GC - Gas Chromatograph
Gas Chromatography - Flame Ionization Detector or GC-FID is a common analytical technique that is widely used in the petrochemical, pharmaceutical and natural gas markets. A flame ionization detector (FID) is a scientific instrument that measures the concentration of organic species in a gas stream. It is frequently used as a detector in gas chromatography. An FID typically uses a Hydrogen/Air flame into which the sample is passed to oxidize organic molecules and produces electrically charged particles (ions). The ions are collected and produce an electrical signal which is then measured. (Source: Global Change Master Directory (GCMD). 2023. GCMD Keywords, Version 16.3 [...] )
