haohan（浩瀚）haohan浩瀚GDX-104甲烷柱3m*1/8

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。

浩瀚色谱（山东）应用技术开发有限公司在HJ/T38-1999基础上做出改进,采用双毛细管柱双FID检测器气相色谱法分别测出废气中总烃和甲烷的含量,两者之差为NMHC的含量(有组织以C计,无组织以CH_4计)。本方法*低检出浓度为0.007mg/m~3,方法的准确度和精密度得到进一步提高,操作快捷方便,在日常监测分析中有很好的适用性。

On the basis of the investigation of the natural background values ​​of the main substances contained in the total non-methane hydrocarbons, the collection of environmental toxicological data, and the monitoring of the current situation of the environment, the current concentrations of the total non-methane hydrocarbons in the ambient air in different regions and the environmental conditions near typical pollution sources were analyzed. etc. for a full evaluation. On the basis of a large amount of measured data and through scientific data analysis methods, a local standard of ambient air quality for non-methane total hydrocarbons with strong practicability and favorable environmental management is proposed, which provides a scientific basis for environmental management.

Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. made improvements on the basis of HJ/T38-1999, using double capillary column double FID detector gas chromatography to measure the content of total hydrocarbons and methane in exhaust gas respectively, the difference between the two is The content of NMHC (organized as C, unorganized as CH_4). The minimum detection concentration of this method is 0.007mg/m~3, the accuracy and precision of the method are further improved, the operation is fast and convenient, and it has good applicability in daily monitoring and analysis.
