A source of contamination in the ultramicro analysis of methyl esters of fatty acids by gas-liquid chromatography

Abstract

Contaminants which could be erroneously identified as methyl esters of fatty acids on gas-liquid chromatographic (GLC) analysis were traced to anhydrous methanolic HCl used for methanolysis. Further studies indicated that the artifacts are not esters of carboxylic acids even though they mimic them on GLC analysis.
