The RACK-WM-H2-3300 series use:

- The latest polymer electrolyte membrane (PEM) technology to produce pure hydrogen.
- The exclusive double gas column dryer regeneration system to eliminate all down time for maintenance that is typical of other systems on the market, guaranteeing the best hydrogen purity at all times.

The touch screen LCD interface provides simple and user-friendly management of all functions on the unit.

Improved chromatograph result
The use of hydrogen as a carrier gas allows lower temperature elution, thus extending the life of the chromatograph column. Hydrogen as a carrier gas is faster and more sensitive than the more-expensive helium. Run time savings of 25% to 35% without a decline in resolution.

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 safety
The very limited internal volume (less than 50 ml) allows safe use of the gas generators where the use of cylinders is risky or prohibited. The application of tested safety technologies stops the unit in the event of leaks or malfunctions.

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.


  • Patented gas/water separator electronically controlled
