摘要
研制了一种采用微波等离子体检测器的便携式气相色谱仪。仪器由两部分组成,分装在两个手提箱中。检测器用黄铜制成,外径22mm、内径18mm。腔体体积可用金属螺钉调节,以获得最佳工作状态.介绍了仪器的原理、结构、特点和分析性能.对一些化合物的测定结果表明,敏感度可达10^(-11)克/秒(苯)。仪器可用来作空气中多种挥发性有机化合物和无机气体的现场测定.
A portable gas chromatograph with a microwave plasma ionization detector was developed. It consists of two parts packed separately in two cases. The detector is made of brass. The Outer diameter of the cavity is 22mm and inner diameter 18mm. The volume of the cavity is adjustable to obtain best working conditions. The test results of some compounds show that the sensitivity can reach 10^(-11) g/s(benzene). The instrument can be used for on-site determination of volatile organic compounds and inorganic gases in air.
