The Whisper-0 nitrogen generator has been developed to meet specific requirements in terms of flow, purity and pressure in 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. the low pressure drop, just one bar, allows the unit to be connected to an existing dry and oil-fee compressed air source in the lab.

Benefits
Better results from analytical instruments
The constant purity of the nitrogen improves system stability and ensures reproducible results.
Better lab efficiency
The large nitrogen volumes used in analytical labs for LC-MS techniques mean gas bottles are insuffi cient to ensure good lab productivity.
Cost savings
The investment can normally be paid back in less than a year.
No pipeline is required to carry the gas from the storeroom to the lab.
Improved safety
Nitrogen produced at low pressure and at room temperature eliminates the risks relating to high pressure gas bottle use and the handling of liquid nitrogen.
… and simple installation
The Whisper-0 nitrogen generator is very easy to install in the lab.
No power connection is required. Wall-mounted installation saves bench space! |

Membrane separation technique
Compressed air is forced through a hollow fibre membrane, with selective permeation of the different components - nitrogen, oxygen, CO2, water vapour and traces of rare gases - depending on the rate of diffusion. The rate of diffusion of nitrogen through the membrane is slower than the other components, which thus flow outside of the fibre membrane, leaving just nitrogen inside; this is then discharged subsequently, ready for use.
