Introduction
Specac’s standard long pathlength gas cell range is now the new Atmos™ series of metal-bodied fixed-pathlength gas cells. They have been optimized using the latest optical modelling tools to give maximum signal-to-noise.
The Atmos™ range of cells are heatable to 200 °C with the addition of a heating jacket and temperature controller.
Features
- Optimized optical path for unmatched signal-to-noise
- Low cell volume for fast gas exchange
- Ni-coated Al cell bodies for improved thermal transfer from heating jackets. Also holds higher gas pressure than glass.
- Inert stainless-steel mirror substrates and avoidance of glues to prevent outgassing
- 125 psi (8.6 bar) maximum cell pressure
- Retrofittable heating jacket option for up to 200 °C
Applications
Gas detection, measurement, FTIR
