[Micro determination of acrylonitrile in ambient air by gas chromatography].
Acrylonitrile in ambient air was collected by Tenax GC and then thermo-desorbed. It was separated on GDX-502 chromatographic column from other pollutants and determined by flame-ion ization detector. The minimum detectable concentration was 0.01 mg/m3 when 2 L ambient air was collected. The recoveries were 85.6%-105.4% and RSDs were 4.5%-6.2%.
