Abstract: There is provided a kit of parts for assembly into an impactor (100) for aerosol component collection, such as for exhaled breath. The kit of parts is configured such that an impactor component (128) is receivable into the assembly such that, when a sealing component (136) is in a sample collection configuration and an aerosol sample is being received at an aerosol inlet (110) of a housing of the kit, in use, an aerosol flow path (124) of the aerosol sample is directed onto an impaction surface (130) of the impactor component (128) to promote aerosol deposition thereon. The kit of parts is further configured such that the sealing component (136) is changeable in the assembly into a sample containment configuration before removal of the impactor component (128) from the assembly, so as to retain any aerosol components deposited on the impaction surface (130).
