COSMOS ZA Zero Air Generator

HCS free

Zero Air for Gas sensing, GC-FID, GC-FPD, GC-NPD, THA

The COSMOS Zero Air generators produce dry and hydrocarbon-free air, using air from oil-free compressors, to be used as detector gas for GC.

Designed with safety and convenience in mind, this system will eliminating the need for inconvenient high pressure gas cylinders.

This complete turnkey system is engineered with the highest quality components, is easy to install and requires only minimal annual maintenance.

The ergonomic, compact and stackable design makes the Zero Air series the ideal solution for the your GC gas supply.

Product Benefits

BETTER DETECTOR PERFORMANCE

The reduction of hydrocarbons, including methane to < 0.05 ppm decreases the background noise level and gives the baseline much better stability, considerably increasing detector sensitivity and ensuring precise analytical results.

INCREASED LABORATORY EFFICIENCY

A constant, uninterrupted gas supply of guaranteed purity eliminates interruptions of analyses to change cylinders and reduces the amount of instrument re-calibrations required.

SAVE MONEY

The unit only requires connection to a suitable socket and to external source of compressed air. The investment can be paid back in less than one year.

IMPROVED SAFETY

Zero air produced at low pressure and ambient temperature removes the need for high pressure cylinders.

SIMPLE INSTALLATION

Gas generators can be installed in the laboratory, on or under a bench, eliminating the need for long gas lines from cylinders secured elsewhere.

What is an air generator
and how it works?

Air generators are a safer and more convenient alternative to using gas cylinders. Every time you change a gas cylinder, you take the risk of polluting your gas line with contaminants and impurities. Whereas with an air generator once installed, it will always provide a correct and constant gas purity, without worries, adapted to your needs. But how does an air generator work?

The differents Air Purification Technology available

Zero Air
The Zero Air Generator is designed to receive compressed air from an internal or external compressor.

The oil-free compressor delivers air through a high efficiency coalescing inlet filter to trap moisture that could damage the system. The air exiting the filter enters a high-temperature platinum catalyst that oxidizes hydrocarbons and carbon monoxide to < 0.05 ppm. This reduces the background noise and increases the sensitivity of your analyses. Then, an output particle filter is used to prevent any type of particles from entering the analytical instrument.

Option: The Zero Total air generator allows in addition to the reduction of hydrocarbons and carbon monoxide to remove other pollutants such as NOx and SO2. NOx is reduced with a Purafil filter and the other components are removed with an activated carbon filter.

Ultra Zero Air
The Ultra Zero Air Gas Generator uses adsorption technology (PSA) and a palladium catalyst to produce ultra zero air.

The gas generator is designed to take compressed air at 8 bar (116 psi) from an integrated or non-integrated oil-free air compressor.

This compressed air stream is pre-filtered and then passed over the alumina bed currently in purification mode to remove moisture. The outgoing air enters a high-temperature platinum catalyst that oxidizes hydrocarbons and carbon monoxide to < 0.05 ppm.

Option: The Ultra Air Zero Total generator allows in addition to the reduction of hydrocarbons and carbon monoxide to remove other pollutants such as NOx and SO2. The NOx is reduced with a Purafil filter and the other components are removed with an activated carbon filter.

TOC
The gas generator is designed to take pre-filtered compressed air at 8 bar from the existing laboratory supply or via the built-in oil-free compressor. The pre-filtered air enters a high-temperature platinum catalyst which, through oxidation, removes hydrocarbons and carbon monoxide to < 0.05 ppm. CO2 and moisture are remove.
