摘要
将Porapak柱、ChromosorbP柱及5A分子筛柱串联后再并联 ,构成一个无阀切换的二维色谱 ,用于测定烟道气组成 ;一次进样就可分析烟道气中一氧化碳、二氧化碳和氧气等组分 ,该法具有分析速度快、重复性好、准确度高的特点 。
Components of flue gas were determined by two dimensional chromatograph free from switching valve, which consisted of four columns of Porapak S, 5A molecular sieve, chromosorb P and Porapak Q connected by series _ parallel. The contents of components CO, CO2 and O2 in flue gas can be simultaneously determined by injecting sample once. The method is simple, rapid, repeatable and accurate. Hence, it is suitable for practical application.
