摘　　要：传统的对毒害气体的快速现场分析或报警器材具有快速响应、灵敏度高等优点,但是由于缺乏分离手段,不同程度存在抗干扰方面的问题。将快速气相色谱应用于现场快速分析检测,在国外已经屡见不鲜。色谱突出的分离特点使分析的准确性大大增加。本文以现场分离毒害气体为应用点,介绍了适合于现场快速分离检测的色谱仪器和装置、微型柱,关键因素如进样方法、检测器、载气等方面进行了详细分析。Traditional chemical sensor and portable detector have many advantages such as rapid response,high sensitivity and so on.Chemical sensor may have some problem of interfere because of lacking separation means.High speed gas chromatography is widely used in recent year.Outstanding separatation characteristic of Gas chromatography increases accuracy in field analytical system.The instrument of field gas chromatography, separation column,key problem about inject method,detector, carrier gas are reviewed in this paper.Detail character about applied in hazardous gas detection is analyzed in article
