Overview
The ND-H2 and PAR-H2 hydrogen generators utilize advanced polymer electrolyte membrane (PEM) technology to produce high-purity hydrogen. The ND-H2 series employs a desiccant cartridge, while the PAR-H2 series uses a single column dryer with programmable automatic regeneration.

Applications
These generators are suitable for various applications including ionization flame detectors (FID), carrier gas for GC and GC-MS, collisions on ICP-MS, and small fuel-cell cylinder refills.

Benefits and Savings

• Improved Chromatograph Results: Hydrogen as a carrier gas allows for lower temperature elution, extending the chromatograph column's life and offering faster, more sensitive results compared to helium, with run time savings of 25% to 35%.
• Increased Laboratory Efficiency: Provides a constant, uninterrupted supply of high-purity gas, reducing analysis interruptions and instrument recalibrations.
• Improved Safety: The limited internal volume (less than 50 ml) ensures safe operation, with safety technologies to halt the unit in case of leaks or malfunctions.
• Simple Installation: Can be installed in the laboratory, eliminating the need for long gas lines from external cylinders.
