随着天然气的普及使用，检测天然气泄露的仪器和系统越来越受到人们的关注，但天然气无色无味，泄漏不容易察觉，目前，按国际标准要求，城市煤气、天然气等气体的赋臭剂必须使用四氢噻吩（THT），这样当天然气发生泄漏时能够让人及时发觉。四氢噻吩是一种含硫饱和杂环化合物，不易被空气氧化，化学性质稳定，挥发性较低，但总能产生稳定的、不易散发的臭味[4][5]，空气中存在0.02 mg/m3即能闻到，我国天然气中四氢噻吩含量一般在20～50 mg/m3。

　　对于加臭剂浓度的检测是十分必要的,加臭剂的检测主要是通过加臭剂检测仪进行,加臭剂检测技术的原理主要有电化学发生法和气相色谱分析法。

　　With the widespread use of natural gas, instruments and systems for detecting natural gas leaks are receiving increasing attention. However, natural gas is colorless and odorless, and leaks are not easy to detect. Currently, according to international standards, the odorant for gases such as city gas and natural gas must use tetrahydrothiophene (THT), so that when natural gas leaks, it can be detected in a timely manner. Tetrahydrophene is a sulfur-containing saturated heterocyclic compound that is not easily oxidized by air, has stable chemical properties, low volatility, but always produces a stable and difficult to emit odor [4] [5]. It can be smelled in the air at a concentration of 0.02 mg/m3, and the content of tetrahydrothiophene in natural gas in China is generally between 20-50 mg/m3.

　　It is necessary to detect the concentration of odorants. The detection of odorants is mainly carried out through odorant detectors, and the principles of odorant detection technology mainly include electrochemical generation and gas chromatography analysis.

　　The research on rapid detection of natural gas leaks based on gas chromatography technology in Haohan Chromatography has high column efficiency, good separation, and satisfactory results.
