摘要： The present disclosure relates to a system and method for automatic online monitoring of dimethyl sulfide in environment. The method may realize separation of water vapor and the substance to be detected in accordance with the adsorption phase equilibrium principle of substance, thus eliminating the influence of water vapor on detection. The disturbance of other substances in an environmental sample can be eliminated in accordance with the charge or proton transfer principle of molecule ion reaction. Automatic online sampling, preprocessing and sample injection units are configured using valves, numerically controlled motor-driven injectors, flow controllers and a peristaltic pump, so that continuous online detection of DMS in an environmental water sample (e.g., seawater, or lake water) or a gas sample (e.g., atmosphere) can be realized.
