Dedicated total hydrocarbon column for non-methane total hydrocarbon monitoring and analysis
Dedicated total hydrocarbon column for non-methane total hydrocarbon monitoring and analysis

According to the 2015 "State Bulletin of the State of the Environment of China", most cities have an increasing number of days with ozone as their primary pollutant. VOCs in the atmosphere are the most important precursors for ozone generation, and they can also affect PM_ (2.5). They have become the focus of monitoring and control, and have been included in the total amount control system. Shanghai, Guangzhou, Xi'an and other places have adopted non-methane total hydrocarbons as the evaluation index of VOCs.
Tengzhou Haohan Chromatographic Instrument Technology Service Co., Ltd., combined with the actual situation of environmental monitoring and analysis, discussed the sample collection, injection method and sample column of non-methane total hydrocarbons. Good inertness and chemical inertia, and long storage time of the sample; using one injection, dual chromatography column GDX502 / 104, glass microspheres to separate samples at the same time, dual FID detection at the same time, saving time, avoiding errors, faster and accurate.
