Abstract
Systems, devices, and methods for a trace-gas sensor configured to generate a raw detector signal (118) based on a gas sample; an analog processing configured to filter, amplify, lock-in, and/or normalize the generated raw detector signal; analog to digital converters configured to convert the filtered and amplified detector signal to a digital signal; and a drive computer configured to: receive the converted digital signal from the analog to digital converters; and apply a spectroscopic model to the received digital signal to extract one or more properties of the gas sample.
