F-DBS’ hydrogen generators are the alternative to gas cylinders in your laboratory. Purities up to 99.99999 % are available and the generators offer silent operation at pressures up to 10 barg (155 psig).
The PG-H2 hydrogen generators use the latest polymer electrolyte membrane (PEM) technology to produce pure hydrogen.
The PG-H2 series generators are ideal for:
- Ionization flame detector (FID)
- Carrier gas for GC and GC-MS
- Collisions on ICP-MS
- Small fuel-cell cylinder refills
Benefits
Improved chromatograph results
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.
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.
Savings
Hydrogen gas generators avoid the need for expensive installation of gas pipelines from the cylinder storerooms to the labs, as well as the need to repeatedly change the bottles.
Longer analytical column life
The use of hydrogen as a carrier gas allows lower temperature elution, thus extending the life of the chromatograph column.
Lab productivity
Continuous operation 24 hours a day allows maximum lab productivity, cutting dead time for gas bottle changeover and maintenance of the drying system.

Operating diagram
- Hydrogen is produced using distilled or deionized water from hydrolysis, through a polymer membrane.
- Electrolytic dissociation separates the water into its two main components: hydrogen ready for analytical use, and
- oxygen that is released into the air.
- No acid nor alkaline solutions are used in the hydrogen generation cycle.
- The drying filter is easy to remove for regeneration; a signal is shown on the display when filter regeneration is required.
- The exclusive cascading option allows up to 10 units to be connected in series, producing flow-rates of up to 10 litres!
