haohanGDX502填充柱分析固定污染源废气甲烷、总烃和非甲烷总烃2m*3mm

Non-methane hydrocarbon (NMHC) emissions from stationary sources of organized and unorganized emissions: refers to hydrocarbons other than methane (mainly the C2 ~ C8) in general. NMHC in the atmosphere above a certain concentration, in addition to direct harmful to human health, but under certain conditions by the sunlight can produce photochemical smog, environmental and human harm. Monitoring of ambient air and industrial emissions of NMHC There are many ways.
Tengzhou City Technology Co., Ltd. Xiangying analysis developed GDX-502 stainless steel packed columns in stationary source emission total hydrocarbon, methane, oxygen, resulting in peak NMHC (NMHC) content. When chromatographic injection volume of 1.0 mL, a concentration detection method is 4 × 10-2mg / m3, quantitative assay concentration range was 0.12 ~ 32 mg / m3.

固定污染源有组织排放和无组织排放的非甲烷总烃(NMHC):指除甲烷以外的碳氢化合物(其中主要是C2～C8)的总称。大气中的NMHC超过一定浓度,除直接对人体健康有害外,在一定条件下经日光照射还能产生光化学烟雾,对环境和人类造成危害。监测环境空气和工业废气中的NMHC有许多方法。

浩瀚色谱（山东）应用技术开发有限公司研发出GDX-502不锈钢填充柱，分析固定污染源排气中总烃、甲烷、氧峰从而得到非甲烷总烃(NMHC)含量。当色谱进样量为1.0 mL时,方法的检出浓度为4×10-2mg/m3,方法的定量检定浓度范围为0.12～32 mg/m3。
