摘要
建立了一种采用Tenax TA固体吸附/热脱附与气相色谱仪联用测定环境空气中苯系物的方法;该方法校准曲线线性良好,采样体积为1 L时,各组分检出限为2.7×10-4~4.7×10-4mg/m3;该方法灵敏度高,精确可靠,操作便捷,适用于环境空气中苯系物的测定。
In this paper,a method for determining benzene series in ambient air by Tenax TA solid adsorption/thermal desorption combined with gas chromatography was established.The calibration curve of this method has good linearity.When the sampling volume is 1 L,the detection limit of each component is 2.7×10-4 to 4.7×10-4 mg/m3.This method is sensitive,accurate,reliable and easy to operate,and it is suitable for the determination of benzene series in ambient air.
