PGCM-5500A Environmental Air Non Methane Total Hydrocarbon Online Monitoring System
VOCs are important precursors of particulate matter PM2.5 and ozone O3, making their reduction an important task for air pollution control and online monitoring during the 14th Five Year Plan period. The two indicators of total air volume, sulfur dioxide and nitrogen oxides, have been basically solved. During the 14th Five Year Plan, the monitoring of SO2 in the air has been replaced with VOCs.
The Outline of the Ecological Environment Monitoring Plan (2020-2035) also mentions the improvement of the national atmospheric particulate matter chemical composition and photochemical assessment monitoring network, covering all prefecture level and above cities, and conducting unified monitoring of non methane total hydrocarbons. Key areas, cities with ozone exceeding standards, and key industrial parks are required to carry out VOCs component monitoring.
The HPGC-1000 environmental air non methane total hydrocarbon online gas chromatograph independently developed by Hopps fully complies with the technical requirements of HJ 604, HJ 1010, DB31/T 1090 standards, and is suitable for various fields of environmental air quality monitoring such as factories and air stations. The product can effectively determine the content of non methane total hydrocarbons in ambient air, with a detection limit of ppb level.

Product principle
The instrument uses direct measurement method and built-in enrichment unit to measure ppb level non methane total hydrocarbons.
Product Features
The unique positive pressure gas bath heating method of the analyzer has a fast heating rate, a more uniform temperature inside the column box, and can quickly eliminate potential hazardous substances; The direct heating detector can effectively avoid the loss of high boiling point and high concentration samples, and adopts a travel switch and pressure monitoring to achieve dual safety protection.
The carrier gas, combustion gas, and combustion assisting gas are all controlled by electronic flow control. We have independently developed high-quality EPC and PID algorithm regulation, which has strong anti-interference ability and high control accuracy. The control accuracy can reach ± 0.01ml/min;
Adopting an intelligent chromatographic processing system, it has functions such as intelligent recognition, automatic recording, automatic diagnosis, automatic alarm, data acquisition, processing, display, storage, query and output of spectra;
The analyzer has various application designs such as conventional and explosion-proof, and can be applied to areas with different safety requirements;
