Web8.2 Gas Chromatography (GC) GC with flame-ionization detection (FID) is widely used for lipids analysis. Sample preparation for this technique includes preseparation of lipid classes, hydrolysis, derivatization, or pyrolysis. GC can also be used for direct separation of triacylglycerols based on the carbon number (CN). WebMay 15, 2008 · The flame ionization detector (FID) quantifies small concentrations of organic compounds by flame ionization of hydrocarbons and measurement of the resulting ion current. The ion current represents the number of carbon atoms in the sample gas. The miniaturization of the FID by MEMS technology (µFID) is expected to increase its use, …
