The ARCoptix GASEX OEM module represents a highly efficient, rugged and fully integrated solution for gas spectroscopy.  The OEM010 module is coupled to a low volume (0.2L) heated (up to 200°C) gas cell, in which light experiences multiple reflections, resulting in an integrated optical path of 5m with more than 50% transmission. The cell's internal optics is rhodium and gold coated, making it extremely resistant against most chemicals including acid gases such as HF, HCl, HBr.

Working principle:  The Gasex System consist of an interferometer module including also the MCT detector and an IR light source and a Multi-reflection gas cell. The light is produced by a black body radiation module and modulated by a dual corner cube interferometer. The light is then coupled into the Gas cell (where the gas to be analyzed is injected) where it is reflected back and forth 32 times. Finally the light focused on the MCT detector.

Key Features

• Compact, rugged and high-performance FTIR module with 4TE-MCT detector;
• Long path (5m), low volume (0.2L) heated gas cell seamlessly matched to the FTIR for high sensitivity and very short response time;
• Rhodium coated chemically resistant optics;
• Most compact FTIR Gas Analyzer Bench on the market, only 40cm x 19cm x 12cm and 3.9 kg in weight.
• Resolution of 0.5 cm-1 (IUPAC definition) to match the newest regulations in the area of emission measurements.
• 0.7 scan per second rate.
• Mechanical outline identical to that of previous models – in order to facilitate an upgrade of previously developed applications – if needed.
• Modern and very stable data acquisition software solution, extending the field of application to Linux based systems.
• Optionally an on-board embedded computer (Toradex single board) featuring the spectral acquisition.
• On board measurements of essential physical parameters like the cell temperature, atmospheric pressure and differential pressure in the gas cell allowing for data correction for these parameters.
