GDX-104 column
GDX-104 column details:

Non-methane hydrocarbons (NMHC) usually refer to all volatile hydrocarbons except methane (mainly C2~C8), also known as total non-methane hydrocarbons. The NMHC in the atmosphere exceeds a certain concentration, in addition to being directly harmful to human health, it can also produce photochemical smog under sunlight under certain conditions, causing harm to the environment and humans.
Tengzhou Haohan Chromatography Instrument Technology Service Co., Ltd. developed a GDX-104 stainless steel packed column, using "Air and Exhaust Gas Monitoring and Analysis Method (Fourth Edition Supplement)" P587~P589 Total Hydrocarbon and Non-Methane Total Hydrocarbon Determination Method 1 ) The six-port valve quantitative loop sampling is used to determine the concentration of non-methane total hydrocarbons in the ambient air and exhaust gas, and the instrument conditions are optimized.The detection limit of the method is 0.13 mg/m3, and the relative standard deviation of the standard sample total hydrocarbons is 0.4% The relative standard deviation of methane is 1.2%, the recovery rate of total hydrocarbons is 100.9~101.6%, and the recovery rate of methane is 102.4~102.6%. The method is simple in operation, fast in analysis and satisfactory in experimental results.
