摘要
用活性碳吸附管采集大气中的苯系物 ,二氯甲烷替代二硫化碳作为脱附剂 ,毛细管气相色谱分离分析。 F ID测定苯系物的相关系数均为 0 .999,仪器最小检出量可达 0 .1 n g,方法精密度可达 1 .9%～ 4 .8% ,已用于室内空气中苯系物含量的测定。
BTEX in air were adsorbed by active carbon tube, replaced carbon bisu lfide by dichloromethane as reagent,analyzed by using Capillary GC-FID .The wh ole procedure is just 15 minutes, and the minimum detection limits reach 0.1 ng. It has been applied to the determination of BTEX in indoor air.
