Abstract

A simple gas bubbling system for removal of dissolved oxygen in micellar and surfactant solutions is described. The cell design allows for a continuous rapid flow of a purge gas through a surfactant solution without loss of fluid in spite of severe foaming. A long-necked cell with a conical top causes the bubbles to rupture without overflowing, and the fluid returns to the bulk solution. The cell offers numerous advantages over freeze pump thaw and other methods of deoxygenation in terms of speed, ease of sample preparation, and cost.
