The oxygen contents in YBa2CuaOz samples have been determined by two wet chemical redox methods, i.e. by Coulometric and iodometric tirations. Three different samples, synthesized by solgel, UF catalyst and 0, hot-isostatic-press (HIP) techniques, are studied. The results of the two titration methods agree well with each other for all samples. The oxygen content z appears to be dependent on the oxygen pressure applied during the synthesis, since z values slightly below the stoichiometric number of 8.00 have been obtained for the samples prepared under 1 atm oxygen pressure, while for the O2 HIP treated sample the ObSeNed oxygen content is z = 8.00 f 0.01.
