MINI-WHISPER Hybrid Nitrogen generator

Description
The Chemtron Gas Whisper-0 Hybrid Nitrogen + Air can produce up to 120 L/min of high purity LC/MS grade nitrogen at pressures up to 8 barg (116 psig). These generators are engineered to transform standard compressed air into a safe regulated nitrogen and high purity air supply with minimal operator attention and maintenance. Nitrogen is produced by utilizing a combination of filtration and membrane separation technologies. A standard supply of compressed air is filtered by high efficiency coalescing filters to remove all contaminants down to 0.1 micron. A unique proprietary membrane then separates the air into a concentrated nitrogen stream. Air is purified using a unique air purification membrane removing contamination and water.

Membrane technology offers some unique performance benefits for LC/MS users including phthalate free nitrogen, silent operation, no moving parts and no electrical requirements. The generator can be installed directly in the laboratory either floor or walled mounted and requires minimal operator attention or maintenance. The generator are designed to run continuously providing a clean, dry high purity nitrogen supply.

Membrane separation technique
Compressed air is forced through a hollow fiber membrane, with selective permeation of the different components – nitrogen, oxygen, CO2, water vapor and traces of rare gases – depending on the rate of diffusion.
A quantity of incoming air, after a 3-step filtering procedure, is dried through a fiber membrane column. The customer has also a source of dried filtered air in case of analysis that requires it.

MINI WHISPER OPERATING DIAGRAM
Membrane separation technique:
Compressed air is forced through a hollow fiber membrane, with selective permeation of the different components – nitrogen, oxygen, carbon dioxide,water vapor 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 fiber membrane. Just nitrogen remains inside which is then subsequently discharged, ready for use.
