The Gas Chromatography of Fatty Acids and Related Long Chain Compounds on Phosphoric Acid Treated Columns

Abstract

The gas chromatography of unesterified fatty acids has long been a problem of great interest. It was found that columns with polyester and phosphoric acid as the liquid phase gave well defined, symmetrical peaks with fatty acids. The quantitative aspects of these peaks were studied. The phosphoric acid columns proved to be useful for chromatographing other long chain materials including nitriles, amides and sulfonated compounds.
