低温甲醇洗中痕量硫化氢含量的测定硫专用柱HH一sulfide-III 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er硫等9种硫化物的测定
低温甲醇洗采用德国林德公司和鲁奇公司联合开发的一种气体净化工艺，该工艺以冷甲醇为吸收剂，利用甲醇在低温下对酸性其溶解度极大的优良特性，脱除原料气中的酸性气体。要求尾气中的硫化氢含量低于50.00×10-6。传统硫化物分析方法有硫化氢检测管法、气相色谱 FPD (火焰光度检测器)法等，但这些方法都有着其局限性，硫化氢检测管法zui低量程为(0-200)×10-6，抽气量要求为50 mL，成本低、操作简单，但选择性差，准确性有待商榷。气相色谱 FPD (火焰光度检测器)法适于分析含量在10×10-6以上硫化物的测定。
浩瀚色谱（山东）应用技术开发有限公司采用气相色谱 SCD(硫化学发光检测器)法测定气体中硫化物含量能达到0.05×10-6以上。

Determination of Trace Hydrogen Sulfide Content in Low Temperature Methanol Washing Sulfur Special Column HH-sulfide-III
Determination of trace hydrogen sulfide content in low temperature methanol washing Sulfur special column HH-sulfide-III 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 sulfide, etc.
The low-temperature methanol washing adopts a gas purification process jointly developed by Germany's Linde Company and Luqi Company. This process uses cold methanol as an absorbent and utilizes the excellent property of methanol's great solubility to acidity at low temperature to remove the raw material gas. of acid gases. The hydrogen sulfide content in the exhaust gas is required to be lower than 50.00×10-6. Traditional sulfide analysis methods include hydrogen sulfide detection tube method, gas chromatography FPD (flame photometric detector) method, etc., but these methods have their limitations. The minimum range of hydrogen sulfide detection tube method is (0-200) × 10-6 , the pumping volume requirement is 50 mL, the cost is low, the operation is simple, but the selectivity is poor, and the accuracy is questionable. Gas chromatography FPD (flame photometric detector) method is suitable for the determination of sulfides with a content of more than 10 × 10-6.
Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. uses gas chromatography SCD (sulfur chemiluminescence detector) method to determine the sulfide content in the gas, which can reach more than 0.05×10-6.
