Claim:
1. A spectroscopic breath detector for a portable volatile organic compounds testing device, viewed externally as tubular in appearance, for performing spectroscopy of volatile compounds inside the spectroscopic breath detector, 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 replaceable cartridge comprising a heater for heating said cartridge and desorbing the sorbed compounds to form a concentrated sample of volatile organic compounds inside 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 of volatilized organic compounds that forms inside said gas cell, a housing holding parts to form a spectroscopic device wherein said source of electromagnetic radiation and said electromagnetic receiver bracket said gas cell according to the flow through said gas cell, a spectroscopic detector for performing spectroscopy on volatile organic compounds inside said housing, a releasable electrical connector or more for said source of electromagnetic radiation, heater and electromagnetic receiver, wherein said inlet check valve and/or said outlet check valve is an in-line check valve, said inlet check valve and said outlet check valve bracket said gas cell according to the flow through said cartridge, said spectroscopic breath detector configured 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 portable volatile organic compounds testing device such that exhaled breath and/or airflow is accepted and electrical parts are powered.
