A Gas-Liquid Chromatographic Method for Volatile Fatty Acids in Milk

Abstract

Gas-liquid partition chromatography provided a means for a rapid and accurate analysis for the volatile fatty acids in milk. The chromatographic apparatus utilized a 6-ram. I.D. glass column 4 ft. long and packed with Celite 545 containing 25% liquid phase. The liquid phase consisted of silieone-stearic acid (95/5 w/w) mixture. The operating temperature of the colunm was controlled by use of a heating jacket through which glycerol could be circulated.
