Abstract
Abstract The gas chromatographic determination of carbonyl compounds in a contaminated air sample via their thiosemicarbazone was studied. As the method utilizes the selective detectability of the flame photometric detector for the sulfur compound, the isolation of the sulfur-containing derivatives of the carbonyl compounds is not required; this eliminates the inaccuracy stemming from the isolation of the derivatives from the sample solution. The isolation and subsequent regeneration of the carbonyl compound was carded out via the thiosemicarbazone metal complex; this affords a practical method of preparing the sample required for the identification of the individual carbonyl compound.
