HH一sulfide-III 环境空气中恶臭硫化物成分分析硫专用柱

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

原硫化物是一Z类典型的恶臭物质,其特点是活性高,不易储存,因此适宜的储存条件对还原硫化物的准确测定具有重要意义.

浩瀚色谱（山东）应用技术开发有限公司采用冷阱预浓缩-气相色谱/质谱联用法测定环境空气中硫化氢、甲硫醇、甲硫醚、二硫化碳、二甲二硫、噻吩等6种硫化物,讨论了采样容器材质的影响。方法线性良好,6种硫化物的检出限为1.0μg/m3～5.0μg/m3,混合标准气平行测定的RSD≤8.1%,加标回收率为93.5%～97.3%。

Special column for sulfur for the analysis of malodorous sulfur compounds in ambient air 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.

Original sulfide is a typical type of odorous substance, which is characterized by high activity and difficult to store. Therefore, suitable storage conditions are of great significance for the accurate determination of reduced sulfide.

Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. uses cold trap preconcentration-gas chromatography/mass spectrometry to determine 6 kinds of sulfides such as hydrogen sulfide, methyl mercaptan, methyl sulfide, carbon disulfide, dimethyl disulfide, thiophene and other sulfides in ambient air , discusses the influence of sampling vessel material. The linearity of the method was good, the detection limits of the six sulfides were 1.0μg/m3～5.0μg/m3, the RSD of the mixed standard gas parallel determination was less than 8.1%, and the standard addition recovery was 93.5%～97.3%.
