Under the action of the pump, the sample air will deposit the particles separated from the cutter on the sampling filter membrane. After the mass increment is weighed by the oscillating balance, the basic mass concentration can be obtained by calculating the volume of sample gas in this period. In the next period, the sample gas will pass through the constant temperature zero gas filter and then through the sampling filter membrane. The mass concentration in this period is the reference mass concentration. The final concentration is the base mass concentration minus the reference mass concentration.
