Porapak Q 填充分析柱及预柱 气相色谱法测定非甲烷总烃的应用的详细资料

气相色谱法测定非甲烷总烃的应用
气相色谱法测定非甲烷总烃的应用 详细信息：

预柱：PQ，0.8m*1/8
分析柱：PORAPAK Q, 1.5M*1/8

非甲烷总烃(NMHC)通常是指除甲烷以外的所有可挥发的碳氢化合物(其中主要是C2-C8)的总称.一般环境空气中非甲烷总烃的含量不高,但随着近年工业的发展,大量废气排入环境空气中.大气中的非甲烷总烃超过一定浓度,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.

浩瀚色谱（山东）应用技术开发有限公司在对非甲烷总烃中包含的主要物质的自然背景值调查、环境毒理数据的收集、环境现状监测的基础上,对不同地区环境空气中非甲烷总烃的现状浓度及典型污染源附近环境状况等进行全面评价。在大量实测数据的基础上,通过科学的数据分析方法,提出一个实用性强、利于环境管理的非甲烷总烃的环境空气质量地方标准,为环境管理提供科学依据。

Application of Gas Chromatography in the Determination of Non-Methane Total Hydrocarbons
Application of Gas Chromatography to Determine Non-Methane Total Hydrocarbons Details:

Pre-column: PQ, 0.8m*1/8
Analytical column: PORAPAK Q, 1.5M*1/8

Non-methane total hydrocarbons (NMHC) usually refers to all volatile hydrocarbons (mainly C2-C8) except methane. Generally, the content of non-methane total hydrocarbons in ambient air is not high, but with the recent industrial With the development of the environment, a large amount of exhaust gas is discharged into the ambient air. The non-methane total hydrocarbons in the atmosphere exceed a certain concentration. In addition to being directly harmful to human health, under certain conditions, sunlight can also produce photochemical smog, which is harmful to the environment and humans.

Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd. has investigated the natural background value of the main substances contained in non-methane total hydrocarbons, collected environmental toxicology data, and monitored the current situation of the environment. The current concentration of total methane hydrocarbons and the environmental conditions near typical pollution sources are comprehensively evaluated. On the basis of a large number of measured data, through scientific data analysis methods, a practical and environmental management non-methane total hydrocarbon ambient air quality local standard is proposed, which provides a scientific basis for environmental management.
