Determination of Vapor-Phase Carbonyls by High-Pressure Liquid Chromatography

Abstract
Methods have been developed for the trapping and quantitative analysis of low molecular weight carbonyls in complex gas phase mixtures. Formaldehyde, acetaldehyde, acrolein, and acetone are separated as the 2-4-dinitrophenylhydrazones with a sensitivity of less than 10 ppb. The separation can be done on a variety of commercial C18 reverse-phase columns.
