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

本标准适用于恶臭污染源排气和环境空气中硫化氢、甲硫醇、甲硫醚和二甲二硫的同时测定。

浩瀚色谱（山东）应用技术开发有限公司采用苏玛罐采样、冷阱预浓缩处理样品、气相色谱质谱联用法测定环境空气中的甲硫醇、乙硫醇、甲硫醚、乙硫醚、甲乙硫醚、二甲二硫、二硫化碳等7种恶臭硫化物。结果表明,该方法的线性较好,7种硫化物的检出限为8.0×10-4~1.4×10-3mg/m3,混合标准气体平行测定时RSD范围在3.32%~6.17%,加标回收率为100%~117%。该方法对于环境空气恶臭硫化物的测定准确,能够用于常规环境空气中恶臭硫化物的分析检测。

GB/T 14678-1993 Air quality-Determination of hydrogen sulfide, methyl mercaptan, methyl sulfide and dimethyl disulfide-Gas chromatography
GB/T 14678-1993 Air quality-Determination of hydrogen sulfide, methyl mercaptan, methyl sulfide and dimethyl disulfide-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 sulfide, etc.



This standard applies to the simultaneous determination of hydrogen sulfide, methyl mercaptan, methyl sulfide and dimethyl disulfide in odor pollution source exhaust gas and ambient air.

Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. uses Summa tank sampling, cold trap pre-concentration to process samples, and gas chromatography-mass spectrometry for the determination of methyl mercaptan, ethyl mercaptan, methyl sulfide, ethyl sulfide, methyl ethyl sulfide in ambient air 7 kinds of odorous sulfides such as sulfide, dimethyl disulfide and carbon disulfide. The results show that the linearity of the method is good, the detection limits of seven sulfides are 8.0×10-4~1.4×10-3 mg/m3, and the RSD range of the mixed standard gas is 3.32%~6.17%. The recoveries ranged from 100% to 117%. The method is accurate and reliable for the determination of malodorous sulfides in ambient air, and can be used for the analysis and detection of malodorous sulfides in conventional ambient air.
