Automated derivatization and “Just-in-Time” determination of fatty acid methyl esters by GC/MS


Every laboratory is under pressure to quickly and consistently deliver accurate results and to provide clear answers faster than ever before while reducing the cost per analysis. Analysis systems that meet these criteria are always welcome. Application scientists from Bespak Europe Ltd. and from Anatune Ltd., both based in the U.K., have provided such a solution for automated derivatization and GC/MS determination of fatty acids. The approach taken to the challenge: Automated sample preparation combined with discrimination free introduction of the derivatized analytes to the GC/MS system. Automated sample preparation in this case includes adding an internal standard and derivatizing the fatty acids.
