The intelligent air/particulate sampler (hereinafter referred to as the sampler) is an essential sampler for collecting samples of total suspended particles (TSP, PM10, PM2.5, etc.) and various gas components (SO2, NOx, etc.) in the atmosphere . The instrument uses the solution absorption method to collect various harmful gases in the ambient atmosphere and indoor air; uses the filter membrane weighing method to capture the total suspended particulates (TSP) and inhalable particles (PM10) or (PM2.5) in the ambient atmosphere. . The new upgrade of the three core systems ensures the reliability of the instrument, improves the stability of the system, and enhances the accuracy of control. There are great improvements in small portability and flow stability, which greatly reduces labor intensity. It can be used for routine and emergency monitoring of gaseous substances and aerosols in environmental protection, health, labor, safety supervision, military, scientific research, education, tes
