Benefits and Savings
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.
Increased laboratory efficiency
A constant, uninterrupted gas supply of guaranteed purity eliminates interruptions of analyses to change cylinders and reduces the amount of instrument re-calibrations required.
The unit only requires connection to a suitable socket and to external source of compressed air for the zero air part.
The investment can be paid back in less than one year.
The very limited internal volume (less than 50 ml for H2) 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.
Gas generators can be installed in the laboratory, on or under a bench, eliminating the need for long gas lines from cylinders secured elsewhere

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 system is different following the model used :
- ND-H2 Series : the desiccant cartridge is easy to remove for replacement or for refilling
- PAR-H2 Series : used a single column dryer with programmable automatic regeneration via an integrated calendar
- WM-H2 Series : no desiccant cartridge maintenance is required : used a double column dryer with automatic regeneration
Zero Air part use three steps to transform ambient air into analytical grade air.
Step 1: Pre-filtration
The external oil-free compressor delivers air through a high efficiency filter that traps any particles that may damage the system. The filter has an automatic purge and traps oil, water and any other particles larger than 5 microns in size.
Step 2: HC and CO trapping
The air leaving the filter enters a high-temperature platinum catalyser, which through oxidation eliminates hydrocarbon molecules down to < 0.05 ppm.
Step 3: Final filtration
A high-efficiency filter is used to prevent any kind of particles from entering the instrument.
