Schedule a consultationProduct Description
The VICI DBS Whisper series delivers a reliable, continuous supply of nitrogen gas using proprietary high-efficiency hollow fiber membrane technology. Designed for LC/MS and related analytical laboratory applications, the Whisper eliminates the need to handle high-pressure gas cylinders by generating nitrogen directly from a dry, oil-free compressed air supply already present in the lab. With a low pressure drop of just 1 barg (14.5 psig), Whisper generators can easily share an existing compressed air line. Each unit features an integrated economy mode as standard, minimal maintenance requirements, and a 2-year warranty.
- Technology: Proprietary hollow fiber membrane separation
- Air Supply Required: External dry, oil-free compressed air (1 barg / 14.5 psig pressure drop)
- Economy Mode: Integrated as standard
- Warranty: 2 years standard
Applications
LC/MS (nebulizing gas, curtain gas, shield gas, sheath gas, electrospray gas, APCI gas, jet stream gradient), NMR spectroscopy, sample evaporators, ELSD (evaporative light scattering detectors), corona & charged aerosol (CAD) detectors, solvent evaporation
