The F-DGSi’’s FT-IR Purge Gas generators is specifically designed for use with FT-IR spectrometers to provide a purified purge and air bearing gas supply from compressed air.

The unit provides instruments with CO2 free compressed air at less than -70¬°C (-94¬°F) dewpoint with no suspended impurities larger than 0.01 micron 24 hours/day, 7 days/week.

The generator is controlled using the latest in HMI touch screen technology to display the process in real time, inlet/outlet pressures.

Increased laboratory efficiency
A constant, uninterrupted gas supply of guaranteed purity eliminates interruptions of analyses to change cylinders and reduces the amount of instrument re-calibrations required.

Better detector performance
The FT-IR Purge gas generator generates cleaner background spectra in a shorter period of time and more accurate analysis by improving the signal-to-noise ratio.

Improved safety
FT-IR purge gas produced at low pressure and ambient temperature removes the need for high pressure cylinders.

Simple installation

Gas generators can be installed in the laboratory, on or under a bench, eliminating the need for long gas lines from cylinders secured elsewhere.
