Derivatization techniques used for the analysis of volatile aldehydes in air samples are reviewed. Pentafluorobenzyloxime derivatives of aldehydes are useful for gas-chromatographic analysis because the reactions proceed in mild conditions and the derivatives show good volatility. Thiazolidine derivatives have some characteristics; i, e., the reaction is rapid and mild, produces only one derivative from one aldehyde, and the products are selectively detected by NPD. DNPH/HPLC method combined with solid sorbent sampling system is suitable for routine analysis.
