Abstract: An exemplary breath analysis system may include a sampling chamber having a molecule collector disposed therein. The molecule collector may be configured such that volatile organic compounds (VOCs) present in a breath sample introduced to the sampling chamber adhere to the molecule collector. 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 to release at least the portion of the VOCs adhered to the molecule collector. An analysis device (e.g., a mass spectrometer or Terahertz (THz) spectrometer) may identify one or more target VOCs from among at least the portion of the VOCs released from the molecule collector and generate an output representative of the identified target VOC(s). The output may include information that quantitates a concentration of the target VOC(s) with respect to a source of the breath sample.

Abstract: An exemplary breath analysis system may include a sampling chamber having a molecule collector disposed therein. The molecule collector may be configured such that volatile organic compounds (VOCs) present in a breath sample introduced to the sampling chamber adhere to the molecule collector. A heating element may introduce heat within the sampling chamber, causing release of at least a portion of the VOCs adhered to the molecule collector. An analysis device (e.g., a mass spectrometer or Terahertz (THz) spectrometer) may identify one or more target VOCs from among at least the portion of the VOCs released from the molecule collector and generate an output representative of the identified one or more target VOCs. The output may include information that quantitates a concentration of the one or more target VOCs with respect to a source of the breath sample.

Abstract: An exemplary breath analysis system may include a sampling chamber having a molecule collector disposed therein. The molecule collector may be configured such that volatile organic compounds (VOCs) present in a breath sample introduced to the sampling chamber adhere to the molecule collector. A heating element may ramp heat within the sampling chamber, causing release of at least a portion of the VOCs adhered to the molecule collector, lighter and/or less bound VOCs first, heavier and/or more strongly bound VOCs later. An analysis device (e.g., a mass spectrometer or a Terahertz (THz) spectrometer) may identify one or more target VOCs from among at least the portion of the VOCs released from the molecule collector and generate an output representative of the identified target VOC(s). The output may include information that quantitates a concentration of the target VOC(s) with respect to a source of the breath sample.
