Nitrogen Generators

0.5-40L/min, 98-99.999% N2
The Mistral Evolution and Whisper nitrogen generators have been specifically designed to meet the flow, pressure and purity requirements of all the leading LC/MS instrument manufacturers. Nitrogen is produced by either carbon molecular sieve (CMS) or hollow fiber membrane technology, depending on the exact user requirements. Generators are also available with integral compressors, providing a complete ”plug and play“ solution.
MISTRAL Evolution & WHISPER Models:
• Flow rates from 10 to 120 lpm, 98-99.5% N2
• LC/MS grade hydrocarbon free nitrogen
• Pressure up to 8 bar (116 psig)
• Oil free, low noise compressor options
• Special hybrid dry air and nitrogen options –
• For Agilent Microwave Plasma and Sciex
