Assignee: UNIVERSITY OF NORTH TEXAS
Field: Measurement (Instruments)
Classification: CPC G  H | IPC G

Claim 0:
1. A system for analyzing a breath sample, the system comprising:
a sampling chamber;
an inlet coupled to the sampling chamber and configured to receive a breath sample and to provide the breath sample to the sampling chamber;
a molecule collector disposed within the sampling chamber, wherein the molecule collector is configured to adhere to volatile organic compounds (VOCs) present in the breath sample;
a photodiode array configured to excite and/or heat the molecule collector to release at least a portion of the VOCs from the molecule collector;
an analysis device configured to:
identify one or more target VOCs from among the VOCs present in the sampling chamber subsequent to release of at least the portion of the VOCs from the molecule collector; and
generate an output representative of the one or more target VOCs; and

a vacuum pump configured to introduce a vacuum in the analysis device, concurrent with the photodiode array configured to exciting and/or heating the molecule collector, the photodiode array and the vacuum pump also configured to, at least concurrent with generating output representative of the one or more target VOCs, clean the system by the photodiode array further heating the sampling chamber and evacuating the sampling chamber and the analysis device using the vacuum.
