Combined Hydrogen/Air gas generator LC-H2, ND-H2, PAR-H2-ZA can provide both hydrogen gas and zero grade air to FID detectors on
gas chromatographs. Hydrogen gas is produced from deionised water using a proton exchange membrane technology. Zero air is produced by purifying compressed air sourced from the air network to a total hydrocarbon concentration of < 0.05 ppm (measured as methane).  
The H2/AIR station combine the hydrogen serie: LC-H2 and Zero air serie ZA (FID-H2/AIR), ND-H2 and Zero air serie ZA, PAR-H2 and Zero air serie ZA generators in one unit. Units are complete systems with highly reliable components engineered for easy installation, operation, and long term performance.

Applications: Ionization flame detector (FID), Fuel gas and air Flame Ionization Detectors, Flame Photometric Detectors, Total Hydrocarbon Analyzers.

Improved chromatograph result: The reduction of hydrocarbons on zero air part, including methane to <0.05 ppm decreases the background noise level and gives the baseline much better stability, considerably increasing detector sensitivity and ensuring precise analytical results. 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.

Technical specifications is for combined LC-H2 and Zero air serie ZA (FID-H2/AIR).
