Abstract: The device for enrichment of oxygen or oxygen compounds in an oxygen-containing gas mixture (110), comprises two input ports, two primary channels, two secondary channels, two magnetic field-producing devices arranged in the first input port (120), and a planar structure. The primary and the secondary channel are connected with the first input port by a bypass (150), which is formed in such a manner that without the action of a magnetic field, more than 60% of the oxygen-containing gas mixture flowing through the input port, flows into the primary channel. The device for enrichment of oxygen or oxygen compounds in an oxygen-containing gas mixture (110), comprises two input ports, two primary channels, two secondary channels, two magnetic field-producing devices arranged in the first input port (120), and a planar structure. The primary and the secondary channel are connected with the first input port by a bypass (150), which is formed in such a manner that without the action of a magnetic field, more than 60% of the oxygen-containing gas mixture flowing through the input port, flows into the primary channel. The magnetic field-producing device produces more than 50% of a unilateral inhomogeneous magnetic field and is a permanent magnet. The secondary channel (130) exhibits a smaller cross section than the primary channel (140). A height of the secondary channel is equal to that of the primary channel. The width of the secondary channel is smaller than that of the primary channel. The permanent magnet exhibits high coercive field strength and/or a high-energy product, cobalt and platinum. The magnetic field-producing device is designed to electro-dynamically produce the magnetic field and allows the regulation of the oxygen content of the gas mixture depending on the gas flow needed for the electro-dynamic production. The input port, the primary channel and/or the secondary channel exhibit a channel width of 5-100 mu m and a channel height of 20-500 mu m. The planar structure exhibits a carrier layer and a channel-forming layer. An exit of the secondary channel is arranged at a different level than the exit of the primary channel. The device is a separation nozzle, which exhibits a length 0.5-2 mm, width of 0.25-1.5 mm and a height of 0.5-3 mm. A portion of the oxygen-containing gas mixture flowing through the secondary- and second secondary channel, exhibits higher oxygen content than that flowing through the primary- and the second primary channel. Both the ports are connected by a common bypass and both the secondary channels are connected with one another. Both the magnetic field-producing devices are formed by a single magnetic field-producing device. The secondary channel is connected with the second input port. An independent claim is included for a procedure for enriching oxygen or oxygen compound in an oxygen containing gas mixture.
