Anotace	Two cascade impactors, Berner Low Pressure Impactor and modified BLPI (with lower pressure drop through) were characterized experimentally. First, the critical dimensions affecting the collection characteristics were measured for each impactor stage. Second, the stage absolute pressures were determined. Finally, the collection efficiency curves were obtained for all stages covering the size range of 0.026 – 13.7 µm. The collection efficiency of modified impactor was measured using two condensation particle counters (CPC). In addition, both impactors were experimentally tested for their particle losses using the ammonium sulfate particles at dry (15% RH) and wet (>80% RH) conditions. The losses were determined by rinsing sampling foil and corresponding impactor stage (jet plate, walls and spacer ring) by deionized water. Subsequently the ammonium sulphate content in a sample together with rinse water was analyzed using ion chromatography.
