GCMS法测定大气醛类恶臭物质的采样袋适用性研究

摘要:
采用气袋采样-GCMS分析法测定大气中丙醛等5种醛类恶臭物质,对Tedler等5种不同材质采样袋进行适用性研究。结果表明,Tedler 2号采样袋对低浓度醛类回收率影响最小,低浓度醛类在其中能稳定存放12 h,在PVDFs采样袋中低浓度醛类须在6 h内测定,高浓度醛类在Tedler 2号采样袋和PVDFs采样袋中能较稳定地保存24 h,24 h内的回收率在78%以上。

Study on Sampling Bag Applicability in Determination of Aldehyde Odors in Ambient Air Using GCMS Method

Abstract:
Aldehyde odors such as propanal in ambient air were determined using bag sampling -GCMS method, and different bags such as Tedler were studied. The results showed that aldehyde odors of low concentration level were more stable in Tedler 2 sampling bags, and the recovery was stable in 12 hours. Aldehydes of low concentration level in PVDFs bags should be determined in 6 hours. Aldehydes of high concentration level could be stored in Tedler 2 and PVDFs sampling bags for 24 hours, within which the recovery was above 80%.
