日本产在线气相色谱仪柱填料的国产化

Nationalization of Packing Materials of Japanese On-Line Gas Chromatographic Columns for Feed Gas Analysis in Propylene Oxide Production

介绍了用于监测环氧丙烷生产车间原料气组成的日本产在线气相色谱仪柱填料国产化的研制工作。经大量的测试与比较，选出了４种固定相用以代替原进口柱内填充物，经模拟与现场测试，效果好。

The paper reports the nationalization work of the packing materials of on-line gas chromatographic columns made in Japan for the feed gas analysis in propylene oxide production. The system was made of five different columns. The injection of sample gases was controlled by valves. After a lot of tests and compa risons, we select four kinds of stationary phases to replace those of original columns. The application in practical work is satisfactory.
