1 Hydrogen generators

  • New hydrogen generator for generation of ultrapure hydrogen (99.99999%)
  • Ideal for laboratory use
  • Eliminates risks involved in the use of conventional gas cylinders
  • Based on the new, patented electrolysis cell with patented arrangement of electrodes (best possible insulation between the electrodes)
  • Maintenance-free cell
  • Low energy consumption – smaller loss of electrical energy
  • More efficient electrolysis – higher efficiency
  • Less electrode wear

Applications: FID / GC-MS / ICP-MS

ModelFlow rateOrder No.

2 Nitrogen generators

  • Nitrogen generators ensure constant and reliable supply of ultrapure nitrogen to LC-MS systems
  • Utilization of PSA technology
  • ZEFIRO Zero – without compressor
  • Low-noise < 50 dB
  • Little maintenance required – NEW: double interval - now only every 8,000 h
  • Extensive portfolio of models matching all commonly used LC-MS systems

Application: LC-MS / GC-ICP

These are only some examples for our extensive portfolio of models – contact us for more details!

3 Zero air generator

  • Zero air generators produce laboratory grade purified and hydrocarbon free air from an existing in house oil free compressed air supply. Zero Air Generators remove HC pollutants to less than 0.1 ppm, CO to less than 0.1 ppm and all kinds of particles.
  • Increase of analysis accuracy
  • Elimination of the need for inconvenient high-pressure gas cylinders, and the accompanying risks
  • Ready to use – easy to install – minimum maintenance in yearly intervals
  • Low-noise (< 50 dB)
  • Payback period typically < 1 year

Application: GC-FID, GC-FPD, GC-NPD
