摘要
以碳素基体固相微萃取装置顶空采样后直接用于 GC/ MS分析 ,联用 MS谱库检索和标准加入法对某一洗发香波产品中 CCl4进行定性 ,而后以加标法在同样的采样条件和色质条件下对该产品中的 CCl4进行定量测定。方法的线性 :r=0 .998;检测限 :L OD=1.3× 10 - 8(体积分数 ) ,精密度为 5 %～ 9%。
After headspace sampling with apparatus of carbon basal body solid phase microextraction the collected samples were directly measured by the gas chromatography/mass spectrometry (GC/MS) The qualitative analysis of carbon tetrachloride (CCl 4) in a certain kind of shampoo was carried out by searching the data base of mass spectrums and using standard addition method Afterward,under the same conditions of sampling and GC/MS analysis metioned above,the quantitative analysis of CCl 4 in shampoo samples was carried out by standard adding method The correlation coffecient r of linear relationship,detection limit and relative standard deviation of this method was 0 998,1 3×10 -8 (V/V),5%~9% respectively
