ZA4 - The compact Zero Air Generator

ZA4 - The compact Zero Air Generator

Produces a continuous air flow that is free of organic contaminants

  • Hydrocarbon content less than 0.05 ppm as Methane
  • ZA4 delivers 4,000 ml/min at up to 6 bar
  • Economical and safe source of zero air - no manual replacement of cylinders and no ingress of contaminants
  • Avoids batch-to-batch variations in air cylinder quality
  • Without integrated compressor – perfectly matched to the silent Sicolab compressor station with internal membrane dryer

Zero air generators for your analytical applications

Chromalytic ZA4 Zero Air Generators provide a clean and stable source of hydrocarbon-free air for the supply of oxidant gas for GC FID, FPD, AES and NPD detectors. The highest purity of air is essential to ensure low baseline noise and optimal signal-to-noise ratio for sensitive and reproducible analysis on your instrumentation.

 

Hydrocarbon may be present in the air supply from a compressed air source (normally a dedicated compressor or laboratory air system) due to lubricating oil, greases, or from environmental sources such as solvents in use within the laboratory. Compressors located near other equipment, or from external sources such as car fumes also needs to be removed to give the best instrument performance.
