The nitrogen generator has been specifi cally designed to meet the gas flow, purity and pressure requirements of LCMS instruments. It can be used also for solvent evaporation.
The Nitrogen generator use pressure swing adsorption technology (PSA) combined with a pressure management in two steps to produce pure nitrogen gas with a high fl ow, pressure and purity.
The PG-H2 hydrogen generators use the latest polymer electrolyte membrane (PEM) technology to produce pure hydrogen.
The PG-H2 series generators are ideal for:
- Ionization flame detector (FID)
- Carrier gas for GC and GC-MS
- Collisions on ICP-MS
- Small fuel-cell cylinder refills
Benefi ts and savings
Improve analytical instruments performance
Production of a constant fl ow of gas improves the consistency of
the analysis results and hence reproducibility.
Improve laboratory efficiency
The relatively high gas volumes required by LCMS instruments make cylinder supply inappropriate for such applications. A
constant, uninterrupted gas supply eliminates interruptions of analyses to change cylinders.
Improve economy
Quick return on investment < 1 year.
No gas cylinder rental bottles, no price inflation.
The 2-stage pressure design allows the two compressors to work at their optimum pressure range which is reducing the stress on the compressors and as result extending the life time of the
compressors - which is a considerable saving.
Improve safety
Nitrogen produced at low pressure and ambient temperature removes the hazards associated with high pressure cylinders and liquid Dewar’s.

Operating mode
The Nitrogen generator use pressure swing adsorption technology (PSA) combined with a pressure management
in two steps to produce pure nitrogen gas.
This technique uses a bed of carbon molecular sieve (CMS) to selectively remove oxygen and other contaminants from atmospheric air. The bed alternates between purification and regeneration modes to ensure continuous nitrogen production.
The pure N2 collected is then boosted by a second compressor (stage 2) from 3 barg to 8.0 barg, which is
the outlet pressure specification.
This unique engineered air treatment- and compressor management guarantees a long lifetime for all vital components such as the air compressors..
