A simple low cost gas chromatograph for the determination of fatty acids

Abstract

The construction of a chromatograph, conductivity cell and recording conductivity meter, and their application to the determination of the lower fatty acids, formic to caproic acids, is described. The effect of operating variables on the detector and the relationship between acid concentration and detector response are discussed. Limits of detection of 0·001 µg of formic acid and 0·03 µg of caproic acid were found.
