STREAM

Membrane technology without compressor

Reference | STREAM.[Flow rate]
Nitrogen
LC-MS, Sample evaporation, TURBOVAP

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
