摘　　要：我们利用固相微萃取/便携式气质联用监测手段,快速、准确地对甘肃省兰州市西固区某处的低空大气环境进行了实时的检测并发现：大气中存在着大量的苯系物、烷烃、醇以及少量的低分子酮类、酯类化合物。其中每个样品利用固相微萃取富集时间5～10min之间,美国TORION公司的便携气质在检测过程中,每个样品在3min之内就能准确得到结果。由此,固相微萃取多点迅速采样和便携气质快速检测的结合,非常适合环境大气污染快速反应监测、食品中毒事件现场分析、安检安保的实时监测以及野外采样检测等领域的应用,此检测手段的推出,必将得到相关部门的关注。The SPME/Protable GC/MS gives the results in 3min that running the samples from Xigu area, Lanzhou city of Gansu Province. We found： there are benzene compounds, Alcohols, Esters in the lower atmosphere of Xigu Area, Lanzhou city. Now, SPME is a wide range of application on collecting samples, and which can be used to collect the samples multipoint of an area at the same time. So the detection technology of SPME/Portable GC/MS is very suitable for atmospheric environmental monitoring, food safety, and security field.
