Abstract

A sample collection unit for microbiological air analysis includes a housing and a sample treatment path. The housing has a sample inlet opening, an optical window, and an air outlet opening. The sample treatment path has a conjugation pad, and a test strip with a test area and an absorber section. The sample collection unit also has a device configured to receive a container for a solvent, and a device configured to release the solvent. The sample collection unit is preferably configured as a disposable component in the form of a cartridge. Integration of the container for the solvent in the sample collection unit permits simplification and automation of the corresponding sampling method.
