Polarographic determination of dissolved oxygen in vinyl acetate

polarographic method versus analytical method in determination of dissolved oxygen and n-no3

polarographic method is considered as an alternative laboratory technique for analytical method in determination of dissolved oxygen and n-n03. analytical method is a time consuming technique and is subject to several interferences due to some of constituents in sewage. in this laboratory research, the polar graphic technique with, mercury drop electrodes and titrometric method were applied in ...

Polarographic 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...

Polarographic 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...

Vinyl Acetate

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...
