氧化铝填充柱测高纯硫化氢中的烃 详细信息：

高纯硫化氢是一种重要的电子气体，应用在cvd、掺杂等工艺制备光学、电子器件。硫化氢来源很广泛，石油化工、煤化工等行业产生大量的硫化氢气体，经过富集、精制得到99％左右的工业级硫化氢气体。这些工业级的硫化氢因杂质较高无法满足电子行业的要求。而以硫磺为原料生产的硫化氢生产成本相对较高，品质也较难以直接达到99.99％以上的纯度，也需要再进行提纯。

滕州市浩瀚色谱仪器技术服务有限公司，叙述了一种用用于硫化氢中烃分析的既简便又有效的色谱方法。它采用一报ф3mm×2m10％---Al2O3柱，能分别对硫化氢中的杂质组分如CH4、C2H6、C2H4、C3H4、C2Ⅱ2等进行制定，灵敏度可达0．05ppm/mm，可以满足高纯硫化氢中烃分析的需要，并给出了色谱图。

Alumina Packed Column for Measuring Hydrocarbons in High-purity Hydrogen Sulfide
Alumina packed column for measuring hydrocarbons in high-purity hydrogen sulfide Details:

High-purity hydrogen sulfide is an important electronic gas used in cvd, doping and other processes to prepare optical and electronic devices. Hydrogen sulfide has a wide range of sources. Petrochemical, coal chemical and other industries produce a large amount of hydrogen sulfide gas. After enrichment and purification, about 99% of industrial-grade hydrogen sulfide gas is obtained. These industrial grade hydrogen sulfides cannot meet the requirements of the electronics industry due to their high impurities. The production cost of hydrogen sulfide produced with sulfur as a raw material is relatively high, and the quality is difficult to directly achieve a purity of more than 99.99%, and further purification is required.

Tengzhou Haohan Chromatography Instrument Technology Service Co., Ltd. describes a simple and effective chromatographic method for the analysis of hydrocarbons in hydrogen sulfide. It adopts a ф3mm×2m10%-Al2O3 column, which can separately formulate the impurity components in hydrogen sulfide such as CH4, C2H6, C2H4, C3H4, C2Ⅱ2, etc. The sensitivity can reach 0.05ppm/mm, which can meet the high The analysis of hydrocarbons in pure hydrogen sulfide is required, and the chromatogram is given.
