ZA2A Zero-air generator with integrated compressor
Generation of a continuous air flow that is free of organic impurities
- With integrated A-025 compressor unit from Dürr Technik
- Hydrocarbon content less than 0.05 ppm as methane
- Low baseline noise and an optimal signal-to-noise ratio to ensure sensitive and reproducible analyses
- Oxidizing gas for GC FID, FPD, AES and NPD detectors
- ZA2A delivers 2,000 ml/min at up to 6 bar
- 3 l container
- Smallest footprint on the market
Zero air generator for your analytical applications
The ZA2A zero air generator supplies 2 l/min of hydrocarbon-free air for supplying GC FID, FPD, AES and NPD detectors with oxidizing gas. The A-025 compressor unit forms the heart of this unit and guarantees our customers a durable and service-friendly zero-air generator.
The device is stackable and has the smallest footprint on the market. The zero-air generator can be used for common GC devices from Agilent, Shimadzu, Thermo Fisher or Perkin Elmer.
Ideally suited for the following applications
Typical applications for our zero air generators include the provision of hydrocarbon-free air for detectors used in gas chromatography systems, including
- GC-FID: Gas chromatography with flame ionization 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
