various metal chelates bonded to nitrogen functionalities on the surface of the polymer have been synthesized and found to bind oxygen reversibly. The stationary phases containing [5,5'-(1,2-ethanediyldinitrilo)-bis(2,2,7-trimethyl-3-octanonato)]cobalt(II) were found to be the most suitable of the phases investigated for separating oxygen for argon, nitrogen, and carbonmonoxide. At ambient temperatures,
