摘要
采用气相色谱-质谱法测定汽车材料中7种苯系物的含量。在气相色谱分离中用HP-5MS色谱柱为固定相，在质谱分析中采用全扫描和选择离子监测模式。以氘代苯-D6为内标物。7种苯系物的线性范围均为10～1000ng，检出限（3s）在9～18ng之间。苯系物测定结果的相对标准偏差（n=6）在0．819／5～2．4%之间，加标回收率在99．0％～102％之间。
GCMS was applied to the determination of 7 benzene homologues in automobile materials. HP- 5MS chromatographic column was used for GC separation and modes of full-scanning and selected ion monitoring were adopted in MS determination. Deuterated benzene-D6 was used as internal standard. Linearity ranges of the 7 benzene homologues found were in the same range of 10-1 000 ng with detection limits （3s） in the range of 9- 18 ng. RSD＇s （n：6） of analytical results for the benzene homologues found were in the range of 0. 81 %-2.4%, and values of recovery found by standard addition method were in the range of 99.0 %-102%.
