The biggest advantage of the online analysis technology obtained by Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. is to reduce the detection limit of non-methane total hydrocarbons in atmospheric ambient air and factory boundary ambient air to a new level, so that the lower detection limit of the instrument can reach Sub-ppb level, thus solving the problem of qualitative and quantitative online testing of low concentration of non-methane total hydrocarbons (TVOC) in ambient air. And can separate and analyze methane at the same time. This study determines the reliability and practicality of online analytical instruments. For methane , Non-methane total hydrocarbons have been studied qualitatively and quantitatively, and the calibration linearity, reproducibility, minimum detection limit and other data of the method are given, and the ambient air and plant boundary air have been measured. The results show that the use of this This kind of online analysis technology and instrument has strong analytical practicability, high accuracy, and the analytical detection limit can reach sub-ppb level. It is used for continuous online monitoring to obtain relatively satisfactory results.
