ZA2A - Zero Air Generator with integrated compressor

ZA2A - Zero Air Generator with integrated compressor

Produces a continuous air flow that is free of organic contaminants

  • With integrated compressor aggregate A-025 from Dürr Technik
  • Hydrocarbon content less than 0.05 ppm as Methane
  • Essential to ensure low baseline noise and optimal signal-to-noise ratio for sensitive and reproducible analysis
  • Oxidant gas for GC FID, FPD, AES and NPD detectors
  • ZA2A delivers 2,000 ml/min at up to 6 bar
  • 3 l receiver tank
  • Smallest footprint on the market

Zero air generators for your analytical applications

The Zero Air compressor ZA2A delivers 2 l/min of hydrocarbon-free air for the supply of oxidant gas for GC FID, FPD, AES and NPD detectors. The A-025 compressor aggregate formats the heart of this unit and ensures our customers a durable and service friendly generator.

The unit is stackable and has the smallest footprint on the market. The generator can be used for the common GC devices from Agilent, Shimadzu, Thermo Fisher or Perkin Elmer.

Optimally suited for the following applications

Typical applications include providing zero-hydrocarbon air to detectors used in gas chromatography systems, including

  • GC-FID: Gas chromatography with flame ionisation detector
  • GC-NPD: Gas chromatography with nitrogen-phosphorus detector
  • GC-FPD: Gas chromatography with flame photometric detector
  • GC-AES: Gas chromatography with atomic emission spectrometry
