Abstract
Systems for analyzing fluids (e.g., gases) include a chamber structure with a reflective inner surface, emitters, a primary detector positioned to principally detect electromagnetic energy reflected numerous times through the gas(es) and a calibration detector positioned to detect electromagnetic energy not reflected numerous times through the gas(es). Calibration may be automatically performed. The primary detector relies principally on Raleigh scattering. An optional primary detector may be positioned to principally detect Raman scattered electromagnetic energy.
