随着近年来我国石油化工行业的迅速发展,在线色谱仪因分析准确和分析数据具有实时性,在生产中起着优化操作、控制产品质量等重要作用而被广泛应用。但随着在线色谱仪的使用,其色谱柱逐渐老化,分析时间会逐渐增长,影响到工艺生产。而更换色谱柱费用较高。介绍了通过对在线色谱仪分析方法的优化,缩短了总的分析周期,从而满足了工艺要求。
With the rapid development of petrochemical industry in China in recent years, on-line chromatograph has been widely used for its accurate analysis and real-time analysis of data. It plays an important role in production operation such as optimizing operation and controlling product quality. However, with the use of online chromatography, the column gradually aging, the analysis of time will gradually increase, affecting the process of production. Replacing a column is expensive. Describes the optimization of on-line chromatographic analysis methods to shorten the total analysis cycle to meet the process requirements.
