The system utilizes a combination of compressor, filtration, and membrane separation technologies. High- and low-pressure compressors, filtered by coalescing filters, remove all contaminants down to 0.01 micrometer. Hollow fiber membranes subsequently separate the clean air into a concentrated nitrogen stream and oxygen-enriched permeate stream, which is vented from the system.
     The combination of these technologies produces a continuous, on-demand supply of pure nitrogen. Typical applications include nebulizer gas, chemical and solvent evaporation, instrument purge and supply, evaporated light scattering detector use, and sparging.
