The analyzer contains an optical system with multiple lasers and a series of optical
components that provide an optical path, a heated multi-pass analysis cell, and sample
and outlet ports that can be connected to a gas handling system and control and analysis
electronics. The number of lasers installed depends upon customer requirements. The
complete system operates from 110 to 230 Vac 5050/60 Hz supply.
The analyzer uses mid-infrared optical absorption spectroscopy to measure gas
concentrations. The light sources are lasers, which are operated to produce wavelength
