便携式GC-MS在环境监测中的应用

Application of Portable GC-MS in Environmental Monitoring

便携式气相色谱-质谱联用仪(GC-MS)因其快速、高灵敏度等优点在环境监测中被广泛使用。介绍了HAPSITE ER便携式GC-MS的工作原理、构成、操作过程和注意事项,选择某区域作为研究对象,使用顶空采样装置对区域内水体进行分析,可以初步了解该区域环境现状。

Because of its fast, high sensitivity, the portable gas chromatography-mass spectrometry（GC-MS） has been widely used in the environmental monitoring. The working principle, composition, operating procedures and precautions of HAPSITE ER portable GC-MS are introduced. An area has been chosen as the research object, by using headspace sampling devices to field measurement of water, a preliminary understanding of the regional present situation is obtained.
