HG MINI Hydrogen Gas Generator

A fantastic addition to the lab, the HG MINI hydrogen gas generator is able to generate up to 300 cc/min of hydrogen with purity rates of better than 99.999% and pressure up to 12 bar (174 psi).

This unique hydrogen gas generator includes a cell with polymeric membrane (PEM) using distilled water – no acid of alkaline solutions are involved!

The HG MINI has an innovative static drying system that ensures the maximum grade of hydrogen purity and protects the GC thanks to its unique humidity safe guard.

The core processor automatically checks the system for internal leaks and constantly controls the operation parameters, ensuring full safety for the user.  It’s easy to connect up to 20 HG MINI hydrogen gas generators in parallel using an external control box, and the LED matrix interface provides and simple and instantaneous display of the units’ status.

Key features include:

  • PEM cell technology with integrated tank (patented)
  • Flow rate up to 300 cc/min
  • Pressure up to 12 bar (174psi)
  • USB port standard
  • Purity: 99.999%
  • Static dryer + desiccant column
  • Safety routine and self monitoring
  • Reduced foot print
  • Smart humidity safe guard (patented)
  • High pressure GLS electronically controlled (patented)

Main applications:

  • GC-FID (Gas chromatography – flame ionization detector)
  • GC-NPD (Gas chromatography – nitrogen phosphorous detector)
  • GC-FPD (Gas chromatography – flame photometric detector)
  • GC-PFPD (Gas chromatography – pulsed flame photometric detector)
  • THA (total hydrocarbon analyser)
