Ultra High purity Nitrogen generator

NG SIRIO NC produces laboratory high grade nitrogen for most of the laboratory applications and equipments. Designed with safety and convenience in mind, this system generates purified nitrogen, eliminating the need for inconvenient cumbersome high-pressure gas cylinders.

The NG SIRIO NC removes oxygen from air to less than 1 ppm and HC pollutants to less than 0.1ppm (if the optional CH4 scrubber is installed).

The Ultra Pure Nitrogen is mainly used to feed ICP, ELSD, GC, FTIR and is ideal as nitrogen gas supply for all kind of Laboratory and Chromatography applications.
