Abstract The method of static box was used to explore the influence of sampling flow (Q) on the cut size D50 of particulate matter cutter,including a variety of cyclone cutters of BGI and an impaction-type cutter of Chinese brand.The results showed that no matter which type cyclone cutter,the changes of sampling flow resulted in translation of collection efficiency curve.And the greater the flow rate,the smaller D50.In addition, it was found that the PM1.0,PM2.5 and PM4.0 modes could be switched by changing the flow rate in the same whirlwind cutter,and the sampling flow rate was approximately inversely proportional to D50.For the impaction-type cutter,the square root of D50 was approximately inversely proportional to the sampling flow.It could be used as a rapid evaluation method to quickly estimate the corresponding D50 according to the actual flow rate,which has certain application value.
