Nitrosource, Maxigas, Midigas and Membrane Nitrogen Generators from Parker Domnick Hunter
domnick hunter nitrogen generators cover a wide range of flows and purities to exactly match the needs of applications including LCMS, GC,ICP, ELSD / CAD detector, Circular Dichroism and Sample Evaporation. The optional Generators incorporating an integrated oil free compressor completely eliminate any reliance on a house compressed air supply giving complete security of supply.
The technology used to procure a continuous flow of high purity nitrogen is pressure swing absorption ( PSA ). This technique uses one or two carbon molecular sieves beds (CMS) to eliminate oxygen and other contaminants in the ambient air selectively.
