Abstract

A comprehensive analytical method was developed for determination of N,N-dimethylacetamide (DMAC) in air and exhaust gas by gas chromatography-ion mobility spectrometry. When the concentration of DMAC was 0-5ppm, the standard curve was established by Boltzmann equation method. The detection limit was 0.003ppm and the average recoveries were 93.0% ~ 107%, the method has high sensitivity, good precision and good qualitative ability, and can be better adapted to DMAC laboratory and on-line detection in ambient air and exhaust gas.
