COSMOS hydrogen generators from F-DGSi

COSMOS benchtop series

COSMOS hydrogen generators are an essential and safer alternative to gas cylinders. Today, laboratories are turning to this solution to supply GC detectors and carrier gas. Combining convenience and reliability, our hydrogen generators can thus meet their requirements by offering a constant gas quality and numerous safety features compared to traditional gas sources. Depending on the sensitivity required for your analysis, three models of hydrogen generators are available. The design of these generators have been conceived to be easily integrated on a bench.

COSMOS Rackable series

The Rack Series hydrogen generators have the same technologies and characteristics as a COSMOS generator. However, the design is revised to be integrated in standard size racks (19 inches), which gives them a significant space saving. This system is ideal for laboratories with no space on their bench.

Nitrogen generators

If your laboratory needs high air quality, F-DGSi offers the widest range of zero air, ultra zero air and CO2-free air generators for applications such as GC, TOC and FT-IR analysis. We can offer these generators with or without compressor.

The differents Air Purification Technology available

Zero Air
Uses high-temperature platinum catalyst that oxidizes hydrocarbons and carbon monoxide to < 0.05 ppm. (Option*)
Ultra Zero Air
Uses alumina bed adsorption technology (PSA) to remove moisture and a palladium catalyst that oxidizes hydrocarbons and carbon
monoxide to < 0.05 ppm. (Option*)
TOC
Uses high-temperature platinum catalyst which, through oxidation, removes hydrocarbons and carbon monoxide to < 0.05 ppm. CO2
and moisture are removed via a CO2-free air dryer, producing a clean, dry, high-purity TOC gas stream.
CO2 Removal
The gas generator is designed to take pre-filtered compressed air at 8 bar from the existing laboratory supply or via the built-in oil-free
compressor. The pre-filtered air enters an air dryer to remove CO2 and moisture, producing a clean, dry, CO2-free air stream.

CRYOGEN Liquid Nitrogen generator

As standard, our generators feature a fully automated system, combining oil-free air compression, PSA Nitrogen generation, cryo-cooling, and Helium compression. All controlled via a user-friendly touchscreen. The helium compressor can be cooled using two primary methods: water cooling or air cooling.
