恶臭是指所有刺激人体嗅觉器官、引起不愉快以及损坏生活环境的气体物质。其中有机硫化合物是造成环境恶臭污染的主要原因之一,含硫气体包括二硫化碳、硫醚、硫醇、硫化氢、噻吩、乙硫醇、甲乙硫醚、乙硫醚等有机硫化合物,由于其嗅觉阈值较低，对人体生理系统造成明显不适，并且毒性大对人体健康造成严重危害而极受关注。目前对恶臭检测zui常用的是三点比较式臭袋法，靠人工嗅辨，误差较大，而且无法定性。
有机硫化物存在极性强，化学稳定性差，具有容易吸附和反应的特点，造成普通的检测方法难以检测。目前，国标（gb/t14678-1993）研究了硫化氢、甲硫醇、甲硫醚和二甲er硫等四种有机硫化物成分的测定。其原理为低温浓缩并用气相色谱法分析，但该方法需要专门的浓缩装置，采用液氧浓缩，有一定的危险性，且分析方法中没有考虑到样品中的水蒸气影响，采样步骤繁琐，导致检测结果的稳定性差，所以目前应用范围不广，很难进行批量分析。
浩瀚色谱（山东）应用技术开发有限公司采用硫专用柱HH一sulfide-III研发一种空气中有机硫化物成分的测定方法，本方法能够应对有机硫化物极强的活性及不稳定的特点，同时操作简单，实现快速有效的检测，适用于对空气中有机硫化物的批量分析。

Determination of Organic Sulfide Composition in Air Sulfur Special Column HH-sulfide-III
Determination of Organic Sulfide Composition in Air 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.
Odor refers to all gaseous substances that stimulate the human olfactory organs, cause unpleasantness and damage the living environment. Among them, organic sulfur compounds are one of the main causes of environmental odor pollution. Sulfur-containing gases include carbon disulfide, sulfide, mercaptan, hydrogen sulfide, thiophene, ethanethiol, methyl ethyl sulfide, ethyl sulfide and other organic sulfur compounds. The olfactory threshold is low, which causes obvious discomfort to the human physiological system, and the toxicity is very serious and causes serious harm to human health, which has attracted great attention. At present, the most commonly used method for odor detection is the three-point comparison odor bag method, which relies on manual olfactory identification, which has a large error and cannot be qualitative.
Organic sulfides have strong polarity, poor chemical stability, and are easy to adsorb and react, making it difficult to detect by common detection methods. At present, the national standard (gb/t14678-1993) has studied the determination of four kinds of organic sulfides such as hydrogen sulfide, methyl mercaptan, methyl sulfide and dimethyl er sulfur. The principle is low temperature concentration and gas chromatography analysis, but this method requires a special concentration device, using liquid oxygen concentration, which has certain risks, and the analysis method does not consider the influence of water vapor in the sample, and the sampling steps are cumbersome, resulting in The stability of the test results is poor, so the current application range is not wide, and it is difficult to carry out batch analysis.
Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. uses a special sulfur column HH-sulfide-III to develop a method for the determination of organic sulfides in the air. This method can cope with the extremely strong activity and instability of organic sulfides, and at the same time Simple operation, fast and effective detection, suitable for batch analysis of organic sulfides in the air.
