浩瀚高纯乙烯中微量硫化氢的测定气相色谱仪GC7990

Sulfide content analysis is an important content in the production of petrochemical industry, hydrogen sulfide in industrial gases on the equipment and catalysts, corrosion and toxic effects, through analysis and control before and after the desulfurization of hydrogen sulfide gas content for the desulfurization process to provide a basis is necessary. The determination of trace sulfides in industrial gases has been a challenge, especially the high standard requirements for trace levels of sulfur compounds in the polymerization grade ethylene and propylene.
Analysis of hydrogen sulfide in high purity ethylene gas by gas chromatography with FPD detector. The backflush method can effectively change the column performance, reducing the minimum detection volume, reaching 0.07x10-6mol / mol.
硫化物含量分析是石油化工生产中的重要内容,工业气体中硫化氢对设备及催化剂,有腐蚀和毒害作用,通过分析掌握脱硫前后气体中硫化氢含量,为脱硫工艺提供依据是有必要的。工业气体中痕量硫化物的测定一直是难点,特别是聚合级乙烯和丙烯中痕量硫化合物的高标准要求。
