Spectroscopic breath detector

A spectroscopic breath detector for a volatile organic compounds testing device, viewed externally as tubular in appearance, for performing spectroscopy of contents within, in which the spectroscopic breath detector comprises:

• an electromagnetic receiver for providing an output signal at a signal magnitude proportional to the intensity of electromagnetic energy received,
• an inlet check valve for allowing exhaled breath and/or airflow into
• a disposable and replaceable cartridge comprising
• a gas cell configured for receiving exhaled breath and/or airflow and performing spectroscopy of contents within and
• a reversible sorbent for reversibly sorbing volatile organic compounds, when present, in fluid communication with said gas cell,
• a heater for heating said cartridge and desorbing the sorbed compounds to form a concentrated sample in said gas cell,
• an outlet check valve for allowing exhaled breath and/or airflow to exit said cell after encountering said cartridge,
• a source of electromagnetic radiation for emitting electromagnetic energy, at any wavelengths, to interact with said concentrated sample,
• a releasable electrical connector or more for said source of electromagnetic radiation, heater and electromagnetic receiver,
• wherein said inlet check valve or said outlet check valve is an in-line check valve,
• said inlet check valve and said outlet check valve bracket said cartridge according to the flow through said cartridge,
• said spectroscopic breath detector is configured for reversibly engaging said cartridge or any part, parts, combination of parts, or combinations of parts that include said cartridge and
• further configured for releasably connecting to and bringing in communication a volatile organic compounds testing device such that exhaled breath and/or airflow is accepted, electrical parts are powered and spectroscopy may be performed.
