Abstract

Abstract A rapid, sensitive gas chromatographic method for the separation and detection of microgram and submicrogram quantities of formic, acetic and propionic acids is presented. The procedure involves reaction of microliter volumes of an ethanolic carboxylic acid solution mixture, down to the 0.1 μg/μl concentration level, with an appropriate p-substituted benzyl halide in a sealed capillary melting point tube at 110°. The esters formed in the reaction mixture are then isothermally eluted from a general-purpose OV-17 glass column.
