Whisper-0 & Mini Whisper Nitrogen Generator

The VICI DBS® Whisper-0 nitrogen generator 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 supply with minimal operator attention and maintenance.

Overview

Membrane technology: silent, low maintenance, no electricity.

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.

Membrane technology offers many unique performance benefits for LC/MS users including phthalate free nitrogen, silent operation, no moving parts and no electrical requirements. The generators can be installed directly in the laboratory with the Whisper-0 mounting to the wall and the Whisper-0 Mini to the floor. Both require minimal operator attention or maintenance. The generators are designed to run continuously providing a clean, dry high purity nitrogen supply.

The Mini Whisper right next to an LC/MS system.
