非甲烷总烃(Non-methane Hydrocarbon,简称NMHC)作为大气挥发性有机物(VOCs)的主要成分,是环境污染监测的重要指标。随着仪器仪表技术的提升,用于NMHC浓度检测的非甲烷总烃分析仪也向更精准、便携的方向发展。气相色谱法作为非甲烷总烃分析仪的常用方法,需要在特定的温度和气体流量条件下完成测量。

　　Non methane hydrocarbons (NMHC), as the main component of volatile organic compounds (VOCs) in the atmosphere, are important indicators for environmental pollution monitoring. With the advancement of instrumentation technology, non methane total hydrocarbon analyzers used for NMHC concentration detection are also developing towards greater precision and portability. Gas chromatography, as a commonly used method for non methane total hydrocarbon analyzers, requires measurement to be completed under specific temperature and gas flow conditions.

　　The MS5A methane column developed by Haohan Chromatography has been applied to Tianrui VOC with high column efficiency, good separation, and oxygen does not interfere with methane, resulting in satisfactory results.
