The Atmos™ series comprises long pathlength gas cells designed for infrared spectroscopy of trace gases and vapors. The cells feature fixed pathlengths of 2.5, 5.0, 10.0, and 20.0 meters, providing wide versatility for different analytical requirements. Each cell is individually optimized to maximize optical throughput and signal-to-noise ratio.
Constructed with Ni-coated aluminum bodies for enhanced thermal conductivity and higher pressure tolerance compared to glass, these cells support operation pressures up to 125 psi (80 psi for the 20 m version). The inert stainless-steel mirror substrates with protected gold coating eliminate outgassing by avoiding the use of glues. Cells can be equipped with heating jackets enabling stable operation up to 200 °C, and can include additional monitoring and purge options.
