Abstract
A gas collection apparatus for use by a user includes a housing with an inlet and an outlet to permit a breath sample to flow therethrough. The housing includes a first compartment and a second compartment, a chemo-resistive analysis assembly having a substrate coupled to a sensor array and disposed within the first compartment, the substrate being operably connected to a voltage control unit coupled to the housing to heat the sensor array to a desired temperature, a resistance control unit coupled to the housing to measure resistance in the sensor array, an optical analysis assembly having a light-emitting diode array and a photodiode array coupled to the second compartment, and a processor coupled to the housing and operably connected to the chemo-resistive analysis and optical analysis assemblies.
