haohan分析环境空气 甲烷、总烃和非甲烷总烃毛细管空柱

NMHC (of NMHC) generally refers to all volatile compounds other than methane CH (mainly the C2-C8) of total hydrocarbons. NMHC in the atmosphere above a certain concentration, in addition to direct harmful to human health, but under certain conditions, by exposure to sunlight, can produce photochemical smog, cause harm to humans and the environment, and thus has become a modern industrial city NMHC major air pollutants come from.
Standard air relative measurement of the exhaust gas oxygen content of the atmosphere or to deduct the total hydrocarbon peak interference of oxygen, this method is provided for representing GB in addition to the use of hydrocarbon air means more convenient and accurate.
Tengzhou City Technology Co., Ltd. Xiangying analysis developed XY- capillary column empty, success was measured ambient air methane hydrocarbons and total non-methane hydrocarbons, satisfactory results are welcome.
非甲烷总烃(NMHC)通常是指除甲烷以外的所有可挥发的CH化合物(其中主要是C2-C8)的总烃。大气中的NMHC超过一定的浓度,除直接对人体健康有害外,在一定条件下,经日光照射下,还能产生光化学烟雾,对环境和人类造成危害,因而已成为现代工业城市中的一种主要大气污染物NMHC主要来自。
采用标准空气相对计量大气或废气中氧的含量,以扣除总烃峰中氧的干扰,此方法较国标中所规定的使用除烃空气的装置更方便、准确。
浩瀚色谱研发出XY-毛细管空柱，成功测定了环境空气 甲烷、总烃和非甲烷总烃，结果满意，欢迎选购。
