EUCA - High Purity Nitrogen Station N2 Generator
From Gas Generator
The LNI Schmidlin SA High Purity Nitrogen generators (HP‐N2) produce 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 HP‐N2 removes oxygen from air to less than 10 ppm (HC polluants to less than 0.1ppm if the option is installed). The typical flows are 500 ml/min, 750 ml/min, 1300 ml/min and 4000 ml/min. Includes smart compressor management.
The optional internal pump compresses the ambient air. Once compressed, the air is cooled and dried by an automatic coalescent filter. Air is passed into a dual column pressure swing adsorption (PSA) to remove oxygen. While one of the dryer columns is active, the other is regenerating by back purging the excess Oxygen. The adsorbed oxygen is vented to atmosphere.
Nitrogen is next channelled into an optional stainless steel catalyst chamber where any background hydrocarbons or carbon monoxide are removed to less than 0.1 ppm. A final high‐grade filter is used to remove particulates greater than 0.5 microns. The compressor stops once the tank has reached its upper pressure level and starts again, once the tank has reached its lower pressure level.
The Ultra Pure Nitrogen is mainly used to aliment ICP, ELSD and is ideal as nitrogen gas supply for all kind of Laboratory and Chromatography applications. The device can be set (as option) with an internal Compressor. Due to its original tank management, the compressor will not work continuously and will have an extended life time.
As option, an internal catalytic oven can be installed. With this additional feature, the generated Nitrogen will be free of hydrocarbons. This option is necessary, if the Nitrogen is used to aliment a GC with FID detector.
Application of High Purity Nitrogen:
- ICP / ELSD
- GC / FTIR
