Abstract
The present invention provides methods of collecting and detecting compounds in a human breath sample, comprising: exhaling into a handheld sample collector to absorb at least one breath compound in an exhaled breath collector of said collector; connecting the handheld sample collector to a breath analyzer; transferring the breath compounds from the exhaled breath collector of the sample collector into the breath analyzer; and detecting breath compounds using two or more sensors. The method may be performed to detect breath compounds for determining health or disease diagnosis, or for drug monitoring.
Claims12
A method of collecting and analyzing a human breath sample comprising at least one breath compound, comprising:
- exhaling into a handheld sample collector comprising a sorbent phase, to absorb at least one breath compound;
- placing the handheld sample collector in fluid communication with a breath analyzer;
- transferring at least one breath compound from the sample collector into the breath analyzer for separation on a thermal desorption column;
- detecting at least one compound using two or more polymer-coated surface acoustic wave sensors;
- wherein the handheld sample collector is not in fluid communication with the breath analyzer during the exhaling.
