Nitrogen Gas Generator

ICP, Circular Dichroism, Sample evaporation, Atomic absorption, TURBOVAP, GC-Carrier gas


F-DGSi’s range of laboratory Nitrogen Gas Generators are some of the best designed PSA Nitrogen Gas Generators available, to supply a continuous flow of Nitrogen Gas at a predetermined pressure and purity.

The generator includes internal storage and automatic shut-down on low/no demand of Nitrogen gas. The generator is controlled using the latest in HMI touch screen technology to display the process in real time.

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.


Improved economy

Pure nitrogen gas produced as standard.


Improved safety

Nitrogen produced at low pressure and ambient temperature removes the need for high pressure cylinders.


Security of supply

Integral oil free air compressor as an option guarantees continuous gas supply, independent of in house compressed air supply.


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
