Gas chromatographic analysis of free fatty acids. Part 1. Principles and methodic variants

Abstract

Proceeding from a literature search the problems faced by the today's gas chromatographer concerned with analysis of free fatty acids are summarized. In terms of column technology self-made OV-1/FFAP mixed phase capillary columns are well suited for adequate tailing — free elution of these polar molecules. Whereas fatty acids having two and more carbon atoms can be analyzed in an underivatized state on acidic capillary columns, the involving of formic acid and dicarboxylic acids cells for deactivation procedures.
