Fatty Acid Methyl ester GC-MS Mixture

This mixture contains various fatty acid methyl esters. The mixture is supplied in an amber ampule in which the headspace has been purged with argon to prevent lipid oxidation. This product has been designed for direct use in GC-MS applications. The solution may be serially diluted for preparation of calibrators and QC standards and/or used directly as a system suitability standard or tuning standard. After opening, we recommend that the mixture be transferred immediately to a 1 ml glass screw cap vial, to prevent solvent evaporation, and stored at -20°C. The mixture should be discarded after multiple freeze/thaw cycles.The fatty acid methyl esters represented in this mixture include the ester versions of various important essential fatty acids, as well as endogenous fatty acids, including those that serve as precursors in the production of many other lipids. As a more lipophilic form of the free acid, these lipids are often more amenable for the formulation of fatty acid-containing diets and dietary supplements.Formulation: (Request formulation change), A solution in dichloromethane (1 mg/ml each compound).
