Synthetic air is used as a zero gas in the running and calibration of environment monitoring and test equipment. In fact, It is used as a balance gas in many calibration mixtures. It is also used as an oxidizer for flame ionization detectors in laboratory research and development other application include medical gas mixtures and atomic absorption flame spectrometry.
Zero Air is produced by mixing pure oxygen with pure nitrogen, thereby eliminating all impurities found in ambient air.
Zero Air is extensively used in laboratories calibrating and running test instruments where small levels of sulphur and nitrous oxide can affect the measurement equipment.
