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
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  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.
