Ough YR 1973 UL http://www.ajevonline.org/content/24/3/125.abstract AB A gas-liquid chromatographic (GLC) method for quantitative analysis of certain volatile acetate esters in wines was developed, tested, and described. The principle involved is the use of a polar-glycerol liquid-phase column to separate alcohols and other very polar volatile components from the acetate esters, prior to the esters being quantitized on a Carbowax 20M column. The auxiliary equipment is a small temperature-controlled oven for the glycerol column, a switching valve and appropriate piping, etc., to add make-up gas, and a convenient arrangement to the main GLC oven. Separation of ethyl, n-propyl, isobutyl, and amyl acetate esters from other components was demonstrated. The results could be quantified. An example was presented of acetate ester analysis of a series of fermentations at five temperatures with two grape musts.
