Whisper

The Whisper nitrogen generator has been developed to meet the flow, purity and pressure requirements of LCMS applications. It can also be used for the evaporation of solvents in samples being analyzed. The simple, high efficiency membrane technology separates nitrogen from the other components of a compressed air supply. The low pressure drop (1 bar)  means that the Whisper can share a dry, oil-free compressed air source already 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
Gas bottles are insufficient to ensure good lab productivity.

COST SAVINGS
The equipment cost is normally recovered in less than a year. In addition, no pipeline is required to carry gas from the storeroom to the lab.

IMPROVED SAFETY
Nitrogen produced at low pressure and room temperature eliminates the risks associated with high pressure gas bottles and the handling of liquid nitrogen.

…AND SIMPLE INSTALLATION
The Whisper nitrogen generator is very easy to install in the lab. No power connection is required. It can sit on the bench top or be wall-mounted to save bench space!

OPERATING PRINICPLE
When the compressed air is forced through the hollow fiber membrane, components like oxygen, carbon dioxide, water vapor, and traces of rare gases pass through the membrance.  Nitrogen diffuses through the membrane slower than the other components, so it remains behind, ready for use.
