摘要
本文采用减压法解决了新型双程序柱载气流速过低问题，使测定结果灵敏度提高，保留时间缩短。用于粗苯车间废水中苯系物的测定，回收率为９０３～１０１６，最低检出浓度为００００７～０００１４ｇ／Ｌ。
This paper offers a solution to the lower flowing speed of carrier gas of a new mode gradient loaded column of the two exponent with better sensibility of the test result and with shor tened retention time by decompresion method.This method can used to determine the derivating series of benzene in waste liquor of the synthesized benzene workshop.Its recovery is 90 3～101 6% and the minimum detectable concentration is 0 0007～0 0014g/L.
