Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. develops non-methane total hydrocarbons and benzene series detection devices and detection methods, which belong to the technical field of air pollution detection. It solves the technical problems of complex structure and long detection time of the existing non-methane total hydrocarbons and benzene series detection equipment. A ten-port injection valve and a four-port injection valve are used to switch the gas path structure of two carrier gas channels and one sample gas channel to form three detection states of pretreatment, methane detection and total hydrocarbon benzene series detection. After completing the three detection processes in sequence, the detection of non-methane total hydrocarbons and benzene series can be completed. It has the advantages of simplified structure, high detection result accuracy and short detection time.

Column 1: Total Hydrocarbon Column
2. Methane column: pq
3. Special column for benzene series
