Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. has developed an online monitoring system and monitoring method for the content of non-methane total hydrocarbons in ambient air. The monitoring system includes: a sampling module, a control module, a display terminal, and a detection device. A trap is installed to adsorb non-methane total hydrocarbons, so that the non-methane total hydrocarbons in the sample gas are separated in advance, the separation efficiency and detection accuracy are improved, and the detection values of non-methane total hydrocarbons and methane can be obtained at the same time; The header is heated to make it heat up rapidly, the release rate of non-methane total hydrocarbons increases, the sampling bandwidth is narrowed, the chromatographic peaks of non-methane total hydrocarbons are thin and high, and the detection accuracy is improved; the automatic collection and online detection of ambient air is realized. Real-time monitoring with low detection limit, high detection accuracy and high sensitivity.
