摘要
采用气相色谱-串联质谱法同时测定烟用水基胶中15种邻苯二甲酸酯类化合物的含量。烟用水基胶样品0.300g经2mL水分散,用10mL正己烷萃取5min。在气相色谱分离中用DB-35MS色谱柱为固定相,在质谱分析中采用多反应监测模式。15种邻苯二甲酸酯类化合物的质量浓度均在0.05~5.0 mg·L^(-1)内与其对应的峰面积呈线性关系,方法的检出限(3S/N)为0.006~0.027μg·g^(-1)。在4,20,100μg·g^(-1)等3个浓度水平进行加标回收试验,回收率为87.8%~104%,测定值的相对标准偏差(n=6)为1.3%~6.1%。
GC-MS/MS was applied to the simultaneous determination of 15 phthalic acid esters in cigarette water-borne adhesives. The sample of cigarette water-borne adhesive （0. 300 g） was dispersed with 2 mL of water, and then extracted with 10 mL of n-hexane for 5 min. The DB-35MS chromatographic column was used for GC separation and the multiple reaction monitoring mode was adopted in MS determination. Linear relationships between values of peak area and mass concentration of the 15 phthalic acid esters were all kept in the same range of 0. 05--5.0 mg · L-1 , with detection limits （3S/N） in the range of 0. 006--0. 027 μg · g-1. Tests for recovery were made by standard addition method at the concentration levels of 4, 20, 100 μg · g-1 , giving values of recovery and RSD＇s （n=6） in the ranges of 87.8% --104% and 1.3%--6. 1% respectively.
