Analysis of Adipose Fatty Acids in Blood Utilizing a GC x GC-MS System

When fatty acids are analyzed with a GC-MS, an enormous number of components are detected due to differences in the number of double bonds and isomers of each component. It is impossible to completely separate these using conventional GC/MS analysis.A GCMS-QP2010 Ultra, equipped with a GC x GC modulator, is capable of separating and detecting components that cannot be separated with a conventional GC-MS.This application datasheet investigates the separation of the C18 fatty acids: oleic acid and gamma-linolenic acid.These substances could not be separated using only a 1-dimensional column, but could be separated 2-dimensionally using a GC x GC-MS system.
