- Nitrogen Generator



Nitroxychrom is a gas generator providing high purity (grade : 99.9995%) of nitrogen used as carrier gas dilution gas for autoGC PID (for VOCs) and MEDOR (for sulfur compounds). Associated with internal calibration tubes, it allows to use specific components without oxidation risks.

The NITROXYCHROM Nitrogen Generator is based on the award-winning NitroGenerator and produces flows of up to 200ccVmin of high purity nitrogen, whilst having the smallest footprint of any nitrogen generator on the market. You don't even have to pipe compressed air from other places in the lab the NITROXYCHROM has an optional state-of-the art mini compressor and is still only 48cm high.


NITROXYCHROM employs Pressure swing absorption (PSA) technology with a stand-by system to produce small flows ol very high purity nitrogen when you need it. The compressed air enters the generator via a filter that removes contaminants and bulk moisture via an integrated auto drain. When the control system assess that more nitrogen is required, the solenoid valves open and the pressure is allowed to build in the column containing Carbon Molecular Sieve CMS and a residue catcher.

This sieve absorbs the oxygen and leaves the dry nitrogen free to flow into the reservoir. After this point, the nitrogen is allowed to flow to the application via the pressure and flow regulators.
