多通道并行气相色谱在裂解气分析中的应用

Study on Multichannel Parallel Analysis of Cracking Gases by Gas Chromatography

提出了一种用Agilent 3000便携式气相色谱仪分析裂解气的新方法。通过选择合适的关联通道,建立了外标 (对氢气)和扩展校正归一化(其它组分)并用的定量分析方法。新方法保持了原系统快速、可靠的优势,最大程度减少 了标准气体的使用量,使分析操作更加便利。

A quantitative correcting method developed for Agilent 3000 micro - GC was introduced. The expanding normalization with channel correcting was proposed to calculate the amount of components eluted from three independent GC channels, and an external standard method was used to quantify the amount of hydrogen in the sample. The new method avoided the problem of using standard gas to correct the instrument,and thus made the analytical operation more easy and flexible while retaining the same accuracy with the original technique.
