环境空气非甲烷总烃连续自动监测系统技术规定（试行）HH-NMHC-1甲烷复合柱 详细信息：
名称：甲烷总烃复合柱
规格：1m*1/8
型号：HH-NMHC-1
应用：环境空气非甲烷总烃连续自动监测技术规定（试行）2021
环境空气非甲烷总烃对大气环境和人体健康有重要的影响，也是光化学监测网的重要监测指标之一。生态环境部《关于加强挥发性有机物监测工作的通知》（环办监测函[2020]335号）文件要求“加强VOCs自动监测能力建设，有条件的城市逐步开展NMHC自动监测试点工作”，国内有100余个城市已经开展了环境空气非甲烷总烃自动监测。随着《技术规定》的印发试行，系统安装、验收和运维质控等相关工作开展将有据可依，监测数据的准确性和可靠性会进一步提高，根据试行过程中的反馈意见我们也将不断修订wan善。
为规范环境空气非甲烷总烃连续监测系统安装与验收、日常运维和质量控制等工作，提高环境空气非甲烷总烃自动监测数据质量，环境监测总站联合上海市环境监测中心等单位组成的编制组，研究制定了《环境空气非甲烷总烃连续自动监测系统技术规定（试行）》（以下简称《技术规定》），并于2021年1月印发生态环境监测系统试行。

Technical regulation for continuous automatic monitoring system of non methane hydrocarbon in ambient air (trial) HH-NMHC-1 methane composite column
Technical regulation for continuous automatic monitoring system of non methane total hydrocarbon in ambient air (trial) Detailed information of HH-NMHC-1 methane composite column:
Name: Methane hydrocarbon composite column
Specification: 1m * 1/8
Model: HH-NMHC-1
Application: Technical Regulation for Continuous Automatic Monitoring of Non methane Total Hydrocarbons in Ambient Air (Trial) 2021
Non methane total hydrocarbon in ambient air has an important impact on the atmospheric environment and human health, and is also one of the important monitoring indicators of the photochemical monitoring network. The Notice on Strengthening the Monitoring of Volatile Organic Compounds (HBMH [2020] No. 335) issued by the Ministry of Ecology and Environment requires "to strengthen the automatic monitoring capacity of VOCs, and gradually carry out the pilot work of NMHC automatic monitoring in cities where conditions permit". More than 100 cities in China have carried out automatic monitoring of non methane total hydrocarbons in ambient air. With the issuance and trial implementation of the Technical Regulations, the system installation, acceptance, operation and maintenance quality control and other related work will be based on evidence, the accuracy and reliability of monitoring data will be further improved, and we will constantly revise Wan Shan according to the feedback during the trial implementation process.
In order to standardize the installation and acceptance, daily operation and maintenance, and quality control of the continuous monitoring system for non methane total hydrocarbons in ambient air, and improve the quality of the automatic monitoring data for non methane total hydrocarbons in ambient air, the Environmental Monitoring Station, together with the preparation team of Shanghai Environmental Monitoring Center and other units, has studied and formulated the Technical Regulations for Continuous Automatic Monitoring System for Non methane Total Hydrocarbons in Ambient Air (Trial) (hereinafter referred to as the Technical Regulations), The ecological environment monitoring system will be issued for trial implementation in January 2021.
Haohan Chromatographic (Shandong) Application Technology Development Co., Ltd. has developed and produced the HH-NMHC-1 special packed column for backflushing, the core component of the direct measurement of non methane total hydrocarbons, with high column efficiency, good separation, symmetrical peak type and accurate and reliable results.
