Gas Chromatographic Identification of Aldehydes and Ketones in Toxicological Analyses
A number of methods [1–5] are available for the identification of aldehydes and ketones by gas chromatography (GC). Baker et al  used a column packed with Porapak Q for the direct determination of the lower alcohols, acetone and acetaldehyde, in blood; a similar method was used to identify these same components in milk . The analysis of compounds containing an isolated carbonyl group, as their 2,4 dinitrophenylhydrazones, has been reported [3,4] and in a recent paper the GC analysis of aldehydes and ketones as their acetals and ketals was described .
