摘要
本文利用气相色谱仪与自行设计的微波诱导等离子体离子化检测器(MIPID)组成联用系统,以氩气为载气和工作气体,测定有机溶剂中的水,考察了各种实验参数对测定的影响。对水的敏感度可达1.5×10^(-9)g/s,线性范围是5×10^(-8)～6×10^(-5)g。对有机溶剂中水的测定结果与热导池检测器气相色谱法吻合。
Water contents in organic solvents were determined by GC with MIPD using Ar as carrier gas and support gas. The experimental parameters affecting the determination were examined. The sensitivity of the method is 1. 5 ×19^(-9)g/s, and the linear dynamic range is 5×10^(-8)～ 6 ×10^(-5)g. The results are in accordance with conventional TCD method.
