摘要
多维色谱采用三体系并行分析和预柱反吹技术分析催化裂化炼厂气组成,改进了色谱柱组及分析条件,检测出H2S组分,提高了O2测定的重复性,保证了色谱柱的使用寿命,并对改进后的方法考察了难分离物质对的分离度及方法的重复性。
Multidimensional chromatography using three parallel system analysis and pre column switching-backflushing technique, can make analysis time short, and ensure the service life of the column, and optimize chromatographic column group and analysis conditions. It can separate and detect catalytic cracking refinery gas components, and ensure repeatability and the degree of separation and separation of substance of the difficult components.
