Abstract: A collecting device (200) for collecting airborne particles comprises: a first (202) and second layer (220) spaced apart for forming a particle collection chamber (240; 340) therebetween: wherein inlets (210; 310) and outlets (230; 330) are configured for transporting a flow of air (104) into and out of the particle collection chamber (240; 340) and configured for allowing capturing airborne particles by impaction. The collecting device (200) further comprises at least one liquid access port (260; 260a, 260b; 360a-360h) for filling the particle collection chamber (240; 340) with a reagent; and wherein the particle collection chamber (240; 340) comprises at least one side wall (246; 346) for defining flow of the reagent, such that a first portion (248a; 348a) and a second portion (248b; 348b) of the particle collection chamber (240; 340) are arranged on opposite sides of the at least one side wall (246; 346).
