Gas Generator



Product Description

VICI DBS has been specializing in the design, development, and manufacture of products and accessories for analytical instruments since 1985.

Their innovative gas generators have been developed using microprocessor control and patented designs to create products that have become the leading exemplar of contemporary and reliable hydrogen, nitrogen and zero air generators amongst their kind.

The Whisper nitrogen generator is used in Liquid Chromatography/Mass Spectrometry (LCMS) applications. It can also be used for the evaporation of solvents in samples being analyzed. The simple, highly efficient 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.

Better Results from Your Analytical Instruments & Improved Safety

The consistent purity of the nitrogen in the Whisper improves system stability and ensures reproducible results. The large nitrogen volumes used in analytical labs for LCMS techniques mean the gas bottles used in a lot of other labs are insufficient when it comes to ensuring good lab productivity. Nitrogen produced at low pressure and room pressure eliminates the risks associated with high pressure gas bottles and the handling of liquid nitrogen.

Main Features and Benefits

  • Developed to meet specific requirements for flow, purity and pressure in LCMS applications that also require filtered and dried air
  • Can also be used for the evaporation of solvents in samples being analyzed
  • Generates nitrogen without mechanical parts or electricity
  • Advanced membrane fiber chemistry assures high recovery rate of nitrogen and low compressed air input
  • Minimal maintenance required as the nitrogen membrane regenerates itself
  • Built in economizer saves energy and automatically shuts off compressed air consumption
  • High-efficiency membrane technology allows for the separation of nitrogen from the other components of the compressed air inlet
  • Consistent purity of the nitrogen improves system stability and ensures reproducible results
  • Easy to install, no power connection required
  • Several instruments can be supplied with nitrogen from a single Whisper nitrogen generator
  • Wall-mounted installation option for minimal footprint
