HP6890色谱柱用于环境空气中微量恶臭硫化物的检测

Trace Sulfur Compounds Detection in the air by HP6890 Chromatographic Column

利用HP6890型气相色谱仪进行环境空气中微量恶臭硫化物分析,实验结果表明:分离效果、峰形都很好,实验采用4种柱箱初始温度及升温程序,分别由初始温度70℃升温至90℃、120℃、130℃及由初始温度150℃,最后升温至190℃,相应分析一个样品的时间依次为:130.515min、63.419min、56.359min及11.116min,样品分析时间大大缩短,可提高分析效率。

HP6890 Gas Chromatograph was used to analyze trace sulfur compounds in the air. Four column temperatures and temperature rise procedure was taken in the experiment. The initial temperatures were 70℃、120℃、130℃ and 150℃which all rose to 190℃.The corresponding times of the sample analysis were 130 min、63 min、56 min and 11 min. The result showed that the separation and peak shape were good. It greatly reduces the sample analysis time and promotes analysis efficiency.
