摘要
建立了以十一烷为内标物、测定水性防水涂料中芳香族化合物含量的气相色谱一质谱联用分析方法。采用该方法检测，各芳香族化合物浓度在0．2-100mg/L范围内呈良好的线性关系，相关系数均大于0．998；加标平均回收率为87％～99％，相对标准偏差小于8％。与JC1066-2008标准推荐的静态顶空气相色谱法相比，该方法灵敏度更高，操作更简便。
A method for determination of aromatic compounds in waterborne waterproofing coating has been developed by gas chromatography-mass spectrometry （GC-MS）, which used undecane as internal standard substance. The calibration curves showed good linear relationship and the correlation coefficients were larger than 0.998 when the content of aromatic compounds was in the range of 0.2~100 mg/L. The average recovery was 87%~99% and the relative standard deviation was less than 8%. Compared with the method of static headspace gas chromatography of JC 1066--2008, The GC-MS method is more sensitivity and easier.
