Determination of Carbon Tetrachloride in Shampoo by Solid Phase Microextraction-Gas Chromatography/Mass Spectrometry With Carbon Basal Body / 环境与健康杂志

ABSTRACT

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
