摘要
用自制的间歇气提装置与１０３气相层析仪联用，对４种彩印软包装中的残留溶剂甲苯进行了定量测定，回收率、标准偏差、变异系数分别为９８．２％，１．７２％和１．７５％。该法为不溶性固体材料中的易挥发组分的定量分析提供了可靠、简便的检测手段。
The self-made discontinuous gas extracting device(DGE) is used on line with a 103 chromategraph to determine 4 samples of residual toluene solvent in color-printed foils, and its recovery, standard deviation and variation cofficient are 98. 2%, 1. 72 % and 1. 75% respectively. It provides a reliable and convenient method for the quantitative analysis of volatile components in insoluble solid samples.
