Atmos™ Heatable Long Path Gas Cells by Specac Ltd

Based on the White cell principle of multiple light passes between an arrangement of reflecting mirrors, the Atmos™ series is available with pathlengths between 2.5m to 20m.

Atmos™ series gas cells are suitable for operation in all modern FT-IR spectrometers using Specac Benchmark™ baseplate provided as standard.

Atmos gas cells are metal bodied and factory aligned for physical robustness in demanding environments and may be operated at pressures up to 125 psi. You can an add a heating jacket and the cell can then be heated up to 200°C to prevent condensation of vapors affecting either the measured results or the performance of the cell. The metal body ensures uniform heating across the length of the cell and the heater is retrofittable without the need to remove any installed pipework.

These cells represent the ultimate in sampling accessories for measuring the infrared spectra of gases and vapors. The use of glues and other potential sources of out gassing have been avoided with the body of the gas cells. The cells have also been designed to allow the cell to be opened to clean particulates from the mirrors and easily re-assembled without the need for re-aligned of the optical components.
