Gas chromatography of the component fatty acids with added internal standard can be used to determine a wide variety of neutral and polar lipids after separation by thin-layer chromatography if precautions are taken to minimise losses. Results can be expressed in terms of the relative amounts of fatty acids contained by the lipids or the actual weights and molar amounts of the lipid classes can. Gas-liquid chromatography is primarily a powerful separating tool.
Compounds can be trapped as they emerge from the GLC apparatus for analysis by mass spec Gas-liquid chromatography of lipids carbohydrates and amino acids SpringerLink. Gas chromatography is used in laboratories to measure steroids barbiturates and lipids. Chromatographic technique is also used in the separation of vitamins and proteins.
The actual process of lipid analysis can be complicated by virtue of the characteristics of the lipids themselves. Gas chromatography may be used but many lipids must be derivatized prior to separation and detection. This renders the method labor intensive and inefficient.

Introduction Cholesterol is a lipid constituent found in animal products. The quantitative determination of cholesterol content in foods has become increasingly important for two major reasons. The first is health concern about the role of excess plasma cholesterol on heart- and artery-related disease Kannel Castell Gordon.
In gas chromatography GC the mobile phase is an inert gas eg helium. The stationary phase is a very thin layer of an inert liquid on an inert solid support - such as beads. Lipid classes were determined by thin layer chromatography TLC and on-column gas chromatography with mass spectrometry GCMS.
The fatty acid pattern of total lipids and free fatty acids was analyzed by GCMS in selected ion monitoring SIM mode.
