The Membrane Nitrogen generator has been developed to meet specific requirements in terms of flow, purity and pressure for LC-MS applications. It can also be used for the evaporation of solvents in samples being analysed.
The simple high efficiency membrane technology allows the separation of nitrogen from the other components of the compressed air inlet.
Advantages product
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 ANALYTICAL INSTRUMENTS PERFORMANCE
Production of a constant flow of gas improves the
consistency of the analysis results and hence reproducibility.
IMPROVE ECONOMY
- Quick return on investment < 1 year
- No gas cylinder rental bottles, no price inflation
IMPROVE SAFETY
Nitrogen produced at low pressure and ambient temperature
removes the hazards associated with high pressure cylinders
and liquid Dewar’s
SIMPLE INSTALLATION
Gas generators can be installed in the laboratory, on or
under a bench, eliminating the need for long gas lines from
cylinders secured elsewhere. No power supply is require.
Characteristics
- Flow rate available: 40 to 260 L/min
- Low pressure loss: max 1 bar (14 psi)
- Wall mounted installation: save space in the lab
- No noise: no mechanical parts moving
- No need of electricity supply
- Low maintenance: only to replace the filters once per year
- Gas saving mode: the unit stops automatically when nitrogen is not required
