摘要
本文对微气相色谱分离柱的制造作了介绍,微柱截面近似为宽200μmm、深30μm的矩形.用102G色谱仪分析了几种固定相材料的分离特性,结果表明SE-30能很好地区分酒精和汽油,适合作为汽车的集成酒敏传感器中微色谱分离柱的固定相.
The miniature capillary column is formed by etching a spiral groove at one side surface of a silicon wafer and then hermetically sealing a 95# glass plate to it. The cross section of the resulting column is roughly rectangular, with a width of 200μm and depth of 30μm. The performance of several liquid stationary phase materials has been measured by model 102G chromatograph, Results show that SE-30 can clearly distinguish alcohol from' petrol. So SE-30 is a suitable liquid stationary phase material using for the miniature gas chromatographic column integrated with alcohol sensor system for automobile.
