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.

Sample collection unit, system and method for microbiological air analysis

A sensor for detecting a first component in a gas mixture is disclosed having a gas-sensitive electrode and a catalyst which is arranged on and/or spaced apart from the electrode in a porous carrier ceramic. The catalyst has the effect that a second component in the gas mixture is chemically altered such that the component contributes to no substantial change in the potential of the electrode.

Sensor for detecting a component of a gas mixture

A gas concentration of a gas may be detected from a gas mixture using gas detectors sensitive to the gas. A gas concentration may be measured by a first gas detector at a first operating temperature, and a first signal characteristic of the measured gas concentration may be provided. An operating temperature of the first gas detector may be changed to a second operating temperature, or a second gas detector having the second operating temperature may be provided. A gas concentration may then be measured at the second operating temperature, and a second signal characteristic of the measured gas concentration may be provided. The gas concentration of the gas from the gas mixture may be determined using a first concentration value allocated to the first signal and a second concentration value allocated to the second signal.
