Gas Generator

Hydrogen 19″ Rack Plus


Product Description

VICI DBS has been specializing in the design, development, and manufacture of products and accessories for analytical instruments since 1985.

Their innovative gas generators have been developed using microprocessor control and patented designs to create products that have become the leading exemplar of contemporary and reliable hydrogen, nitrogen and zero air generators amongst their kind.

VICI DBS hydrogen generators offer a safe, economical and convenient alternative to gas cylinders. Utilizing the latest polymer electrolyte membrane (PEM) technology, these units produce consistently high purity hydrogen.

Hydrogen as a carrier gas is faster and more sensitive than the more expensive helium. Experience run-time savings of 25% to 35% without a decline in resolution.

The hydrogen generators 19” Rack Plus series are ideal for:
• Flame ionization detector (FID)
• As a carrier gas for GC and GC-MS (NM version)
• Fast GC (NM version)
• Collisions on ICP-MS
• Small fuel-cell cylinder refills

The new 19” Rack Plus series features an exclusive “No Maintenance” gas column. The cold regeneration system eliminates any possibility of downtime due to maintenance, assuring the best hydrogen purity at all times.

Improved safety and more savings

The very limited internal volume of the Hydrogen 19" Rack Plus (less than 50 ml) allows for the safe use of the unit where the use of cylinders is risky or prohibited. The application of featured and tested safety technologies automatically halts operation of the unit in the event of a leak or malfunction.

Hydrogen gas generators eliminate the need for an expensive installation of gas pipelines from the cylinder storerooms to the labs, as well as the need to repeatedly change the bottles. The result is a more cost-effective solution.

  • H2 Sensor:
    - Provides a real-time bar graph display of the concentration of hydrogen in the GC (gas chromatography) oven
    - If there is leakage to the threshold level, an audible alarm will sound and a flashing display will be seen
    - If the leak continues until the upper limit of hydrogen concentration is reached, the system will automatically stop the hydrogen generator
    - Optional feature is a valve which inactivates an inert gas purge of the GC oven when the upper limit of hydrogen is reached. When normal levels are restored, operations are restarted
