HH一sulfide-III硫专用柱 气相色谱法测定煤气中微量硫化物的详细资料

气相色谱法测定煤气中微量硫化物
气相色谱法测定煤气中微量硫化物 详细信息:

名称:硫化物专用柱

固定相:专用

规格:3m*3mm

型号:HH一sulfide-III

应用:硫化氢,羰基硫,二硫化碳,噻吩,甲硫醚,甲硫醇,乙硫醇,乙硫醚,二甲二硫等9种硫化物的测定


生产甲醇过程中,原料气中微量硫化物是毒害物质之一,一方面必须设法净化,另一方面采用准确、、快速、先进、自动化的分析方法也是相当重要的。 国内外测定硫化物的方法一般采用铂做催化剂用氢气还原法,使有机硫全部还原为硫化氢,再用化学分析方法测得总硫。此方法准确性差,灵敏度低、操作手续繁琐;微库仑法仪器容易损坏,重现性差;将硫化物 。

浩瀚色谱(山东)应用技术开发有限公司用气相色谱法 ,选择脉冲火焰光度检测器 (PFPD) ,在HH一sulfide-III硫色谱柱上分析煤气中的硫化物 .该方法灵敏度高 ,选择性好 ,结果准确 ,相对标准偏差小于 1.1% .

Determination of Trace Sulfide in Gas by Gas Chromatography
Determination of trace sulfides in coal gas by gas chromatography Details:

Name: Special column for sulfide

Stationary Phase: Dedicated

Specifications: 3m*3mm

Model: HH-sulfide-III

Application: Determination of 9 kinds of sulfides such as hydrogen sulfide, carbonyl sulfide, carbon disulfide, thiophene, methyl sulfide, methyl mercaptan, ethyl mercaptan, ethyl sulfide, dimethyl disulfide, etc.


In the process of methanol production, trace sulfides in the feed gas are one of the toxic substances. On the one hand, we must try to purify them. On the other hand, it is also very important to adopt accurate, reliable, rapid, advanced and automatic analysis methods. The method of determination of sulfide at home and abroad generally uses platinum as a catalyst and hydrogen reduction method, so that all organic sulfur is reduced to hydrogen sulfide, and then the total sulfur is measured by chemical analysis method. This method has poor accuracy, low sensitivity, and complicated operation procedures; the microcoulometric instrument is easily damaged and has poor reproducibility;

Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. uses gas chromatography and selects pulsed flame photometric detector (PFPD) to analyze sulfide in gas on HH-sulfide-III sulfur chromatographic column. The method has high sensitivity and good selectivity , the results are accurate, the relative standard deviation is less than 1.1%.
