Fig. 3. Determination of cutoff size of the microchannel using microparticles with continuous size distribution (2–32 µm).
a Bright field images showing the size variation of the microparticles, configuration of the flows, and the sorted particle streams at output. b Measurements of particle size for input sample and samples collected from inner outlet (IO) and outer outlet (OO). The total flow rate was 300 µL/min and the input flow rate ratio (Qs:Qb) was 1:2
