Hollow‐fiber flow field‐flow fractionation (HF FlFFF) was applied for the separation and size characterization of airborne particles which were collected in a municipal area and prefractionated into four different‐diameter intervals >5.0, 2.5–5.0, 1.5–2.5, <1.5 μm) by continuous split‐flow thin (SPLITT) fractionation. Experiments demonstrated the possibility of utilizing a hollow‐fiber module for the high‐performance separation of supramicron‐sized airborne particles at steric/hyperlayer operating mode of HF FlFFF. Eluting particles during HF FlFFF separation were collected at short time intervals (∼10 s) for the microscopic examination. It showed that particle size and size distributions of all SPLITT fractions of airborne particles can be readily obtained using a calibration and that HF FlFFF can be utilized for the size confirmation of the sorted particle fraction during SPLITT fractionation.
