ATD-GC-MS联用分析大气颗粒物中半挥发性有机物(SVOC_s)

Study on Semi - volatile Organic Compounds in Atmospheric Particulates by GC - MS Coupled Automated Thermal Desorber Method

环境样品中的有机污染物种类繁多、结构复杂、含量不等,对其进行分析测试难度很大.近年来,采用气相色谱-质谱联机、气相色谱-红外(GC-IR)联机、液相色谱-质谱(LC-MS)联机以及超临界色谱-质谱联机(SFC-MS)等新技术[1～3],已对许多环境样品中的复杂有机污染物获得了高灵敏度和高选择性的定性、定量分析结果,包括有机污染物的结构信息.……

Automated thermal desorber(ATD) combined gas chromatography and mass spectrometry(GC - MS) was evaluated for determination of semi - volatile organic compounds (SVOCs) in atmospheric particulates which collected with glass fiber filter film. Compared with Soxhlet's extraction, monocyclinc aromatic hydrocarbon, phthalate, paraffin hydrocarbon in atmospheric particulates result was close.
