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 generator 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 aunique 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.

INCREASE EFFICIENCY

The relatively high gas volumes required by LC/MS instruments make cylinder supply inappropriate and liquid nitrogen expensive. A constant, uninterrupted gas supply eliminates interruptions of analyses to change cylinders.
 

RETURN ON INVESTMENT

Payback period can be as short as 12 to 18 months.
 

IMPROVE SAFETY

Nitrogen produced at low pressure and ambient temperature removes the hazards associated with high pressure cylinders and liquid Dewars.
 

ENHANCE PERFORMANCE

Production of a constant flow and pressure of nitrogen improves the consistency of the LC/MS analysis, results and reproducibility.
 

SUPERIOR TECHNOLOGY

The Chemtron Gas membrane nitrogen generator require no electricity, have no moving parts and minimal noise.
 

WHISPER OPERATING DIAGRAM

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.
