Assignee: PROJECT CANARY, PBC
Field: Measurement (Instruments)
Classification: CPC G | IPC G

Claim 0:
1. An air quality monitoring method comprising:
accepting analyte gas into a cell comprising:
a gas trap;

adjusting, via the gas trap, a flow rate of the analyte gas through the cell;
emitting light rays into the analyte gas;
reflecting the light rays into the analyte gas repeatedly across the cell;
directing the light rays across a path within the cell into at least one sensor in response to repeated reflections;
generating a first spectra signal and a second spectra signal in response to directing the light rays into the at least one sensor;
deconvoluting the first spectra signal and the second spectra signal based on properties of a light source emitting the light rays and optical properties of the at least one sensor at current temperature and pressure within the cell to generate a deconvoluted first spectra signal and a deconvoluted second spectra signal; and
determining a gaseous chemical based on the deconvoluted first spectra signal.
