Polarographic Oxygen Electrode
A method has been developed for the continuous monitoring of oxygen tension in solutions and gases. The oxygen is reduced at a platinum surface which is covered with a plastic membrane. The silver-silver oxide reference electrode is also included under the membrane. Drift is less than 10 per cent for a period of days, and temperature compcnsation is possible. A number of uses to which it has be...
متن کاملPolarographic determination of oxygen tension of whole blood.
The purpose of this study is to establish a procedure for the direct determination of oxygen tension of whole blood that requires a smaller sample and simpler manipulation than methods previously reported (1). A procedure has been worked out for determining dissolved plasma oxygen which proved satisfactory in our investigations. Since the success of the application of the proposed polarographic...
متن کاملPolarographic measurement of dissolved oxygen in yeast fermentations.
M1illions of cubic feet of air are sparged daily into a commercial baker's yeast fermentation to fulfill the oxygen demands of the organism. The costs for air compression are sizeable and, in some cases, the capacity of the air supply system may impose restrictions on the number or types of fermentations which can be scheduled. The rate of air supply required for each type of yeast fermentation...
متن کاملDetermination of permeability and diffusivity of oxygen in polymers by polarographic method with inert gas
A modified polarographic method with inert gas for determination of the oxygen permeability in polymers immersed in liquids is described. Owing to the stream of an inert gas towards polymer from the cathode side, lateral oxygen diffusion (edge effects) is minimized. Unlike the standard Fatt method, the method with inert gas is suitable also for thick samples and, therefore, for high-permeable m...
متن کاملPolarographic Methods of Analysis
The polarographic method invented by J. Heyrovsk over 40 years ago has been associated with many successful achievements in many branches of physical and analytical chemistry, particularly in electrochemistry. Following the construction of the polarograph (with the excellent properties of Kuera's dropping mercury electrode incorporated) by Heyrovsk and Shikata, recording the current—voltage cur...
