摘　　要：该文采用苏玛罐采样-低温预浓缩-气象色谱/质谱方法,建立分析固定污染源中35种挥发性卤代烃的方法。废气样品经苏玛罐收集,经过低温预浓缩后,将样品导入气相色谱质谱仪进行测定,并对整个方法进行验证。实验结果表明,35种挥发性卤代烃在0~10 nmol范围内线性良好。当取样量为400 mL时,方法检出限和方法精密度能够满足固定污染源废气中挥发性卤代烃的检测要求。In this paper,a method for the analysis of 35 volatile halogenated hydrocarbons in fixed pollution sources was established by using Suma tank sampling-low temperature preconcentration-meteorological chromatography/mass spectrometry.The waste gas samples were collected by Suma tank and pre-concentrated at low temperature,then the samples were introduced into gas chromatography-mass spectrometer for determination,and the whole method was verified.The experimental results show that 35 volatile halogenated hydrocarbons have good linearity in the range of 0-10 nmol.When the sample volume is 400 mL,the detection limit and precision of the method can meet the detection requirements of volatile halogenated hydrocarbons in waste gas from fixed pollution sources.
