Chromalytic ZA4 - The compact Zero Air Generator without compressor
 
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.
 
Your advantages
Highly efficient precious metal catalyst for effective carbon removal
Ultra-low hydrocarbon content less than 0.05 ppm as methane
Stable baselines and reproducible results
Integrated air filtration down to 0.01 µm for particle removal to protect the
     electronic pressure control components of your GC
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
Compact, stackable benchtop generator with smallest footprint on the market
Intelligent management of the catalytic converter heating for maximum catalytic
      converter service life and lower operating costs.

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
