The Fatty Acid Methyl Esters Standard Mixture is a metabolite mixture comprised of 13 fatty acids. Fatty acid methyl esters are dissolved in chloroform to the stated concentrations of ± 4%. This product was formulated for use as a retention marker for high-throughput GC/MS metabolomic analysis.

Used as a QC sample for GC-MS-based metabolomics studies.

Gas chromatography-mass spectrometry (GC-MS)-based metabolomics is used to identify and quantify small-molecule metabolites such as small acids, alcohols, hydroxyl acids, amino acids, sugars, fatty acids, sterols, catecholamines, drugs, and toxins.

Fatty acid methyl esters used in this standard showed a strong, consistent m/z 87 ion and molecular ions which could be used to differentiate the individual peaks.
