High-purity nitrogen generator Whisper 0-40

for LC/MSfor mass spectrometersfloor-standing

Overview
The Whisper 0-40 Hybrid Nitrogen Generator supplies nitrogen for LC/MS workflows that require filtered, dried air and controlled gas flows for solvent evaporation and electrospray operations. The membrane separation module delivers nitrogen with a low pressure drop (1 barg), enabling use with existing dry, oil-free compressed air sources.

Key features

• Flow rates: curtain gas 40 L/min @ 7 barg (100 psig); exhaust gas 25 L/min @ 4 barg (60 psig); source gas 22 L/min @ 7 barg (100 psig)
• Nitrogen purity: 97%
• Maximum outlet pressure: 7 barg (100 psig)
• Minimal maintenance; no electrical supply required
• Integrated economy mode
• Proprietary membrane technology
• Part number: DB-WN2-0-40-HY
• 2 year standard warranty

Applications

• Supply gas for LC/MS instruments (curtain, nebulizing, sheath, shield, electrospray)
• Evaporation and solvent removal in sample preparation
• Compatible with SCIEX LC/MS, SHIMADZU LC/MS and similar systems
