Abstract

A method for preparing a breath sample for analysis, wherein the breath sample has been collected using a device (1) for collecting aerosol particles in an exhaled airflow; wherein the method comprises the steps: placing the collecting device in a receptacle (10); adding an eluent fluid onto the collecting device in the receptacle in a quantity smaller than or equal to 20 µl; repeating the adding step one or more times; agitating the receptable using a shaker; centrifuging the receptacle using a centrifuge; and removing the collecting device from the receptacle.

Abstract

A device for collecting aerosol particles in an exhaled air flow. The particles may be aerosol particles such as biomarkers or particles related to drugs or other substances formed or found in the alveoli of the lungs. The device comprises an elongate housing with an inner wall and at least four first type partition walls extending substantially perpendicularly from opposite sides of the inner wall to partly cover the cross-section of the housing. The first type partition walls create a labyrinth shaped flow path to divert air flowing from the inlet towards the outlet of the housing in a direction towards opposite inner walls of the housing so that the particles separate from the air flow and attach on the device. The distance between two opposite first type partition walls is smaller than the transverse width of the housing and increases in the flow direction.
