ZA4 - The compact zero-air generator
Generation of a continuous air flow that is free of organic impurities
- 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 bottles and no ingress of contaminants
- Avoids fluctuations in the quality of the air cylinders from batch to batch
- Without integrated compressor - perfectly matched to the low-noise SICOLAB 025 mini compressor station
Do you need a suitable compressed air source?
Chromalytic is part of the Dürr Technik Group. SICOLAB 025 mini - the compressor station from Dürr Technik is ideal as a source of compressed air for the ZA4. SICOLAB 025 mini has been specially developed for the laboratory area - without disturbing the usual work processes and concentration. The oil-free plug-and-play compressor unit with integrated carrying handle offers minimum maintenance and maximum flexibility.
- Oil-free
- Mobile and compact
- Extremely quiet
Zero air generator for your analytical applications
Chromalytic ZA4 zero air generators provide a clean and stable source of hydrocarbon-free air to supply oxidizing gas for GC FID, FPD, AES and NPD detectors. The highest purity of air is essential to ensure low baseline noise and an optimal signal-to-noise ratio for sensitive and reproducible analysis with your instruments.
Hydrocarbons may be present in the air supply from a compressed air source (usually a dedicated compressor or laboratory compressed air system) due to lubricating oil, grease or environmental sources such as solvents used in the laboratory. Compressors located near other equipment or from external sources, such as car exhaust, must also be removed for best equipment performance.
