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.

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
