Transportable and standalone FTIR Gas analysis system ideal for on field measurements. Powerful module for gas analysis, based on our robust and approved "Rocket" FTIR with combined with a 5 meters optical path, low volume ( 0.2 Liter) multi-pass heated cell.

The ARCoptix Gasex modules is the ideal product for system integrators looking for a customized and intergrable system. The Gasex system contains essentially 4 components:

The corrosion resistant gas cell can be heated up to 190 °C, which ensures that the sample stays in gaseous phase (and avoid condensation) even with high concentrations of H2O or corrosive gases. Many gases can be measured simultaneously like CO2, H2O, CO, NH3,NO, NO2, N2O, SO2, CH4, HF, HCl, and VOC´s. Limits of detection are typically around 1ppm and absolute precision of measured concentration is around a few percent (depending also of the quality of the calibrations and measurement conditions).

The heart of the FT-Rocket is dual corner-cube (retro-reflector) interferometer. The two corner-cubes are fixed to a common swinging arm, which rotates to create an optical path difference (with respect to the beam splitter) in the two arms of the interferometer.
This type of design is called a permanently aligned interferometer. This particular arrangement of the interfeormeter is known to be the most robust against vibrations and temperature drifts. It never has to be realigned.
The swinging arm of the interferometer rotates on wear-free flexure system, making this mechanical system extremely robust and durable.

For measuring the movement of the mirrors, a solid-state reference laser is coupled into the interferometer. Compared to classic HeNe lasers, the solid-state lasers that we use are more compact and have a much longer life-time. They have a very low temperature-induced wavelegnth drift and, when kept at constant temperature with a Peltier element, their wavelength can be stabilized to a few PPM, thus providing a very accurate and reproducible wavelength scale. This is crucial for ensuring a day-to-day and unit-to-unit consistency..
