Claim 0:
1. A spectroscopic device for detecting one or more gas species of interest in a gas sample, the device comprising:
a sensing unit that comprises:
a light source module,
a detector module, and
a sample cell between the light source module and the detector module;

wherein the light source module comprises a light source module housing and a light source that is configured to transmit an interrogation light beam along an optical path directed toward the detector module;
wherein the detector module comprises a detector module housing, a detector, and a reference gas;
wherein said detector is in the detector module housing;
wherein the detector is positioned in the optical path such that the optical path extends from the light source through the sample cell and the reference gas toward the detector.
