The membrane dehumidification technology is applied to the continuous monitoring system of atmospheric particulate matter with the oscillating balance method to exchange moisture in high humidity aerosol with dry gas, the long-term stable humidity can be obtained without damaging the original part of the particulate matter. By designing the drying tube of oscillating balance and setting up a testing system to test its effect, the results show that the drying tube can control the humidity of atmospheric particulate matter well, the method can be applied to the continuous automatic monito-ring system of atmospheric particles with oscillating balance, and the measuring accuracy of atmos-pheric particles can be improved.
