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 compressor station SICOLAB 025 mini

Do you need a suitable compressed air source?

SICOLAB 025 mini - the mobile and silent compressor station is ideal as a source of compressed air for the ZA4. The product impresses with its modern design and very low noise level. SICOLAB 025 mini was 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 with maximum flexibility.

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.
