Abstract
An improved electrolytic cell, the electrodes of which can be readily cleaned, and resensitized by the application of fresh electrolyte upon the electrodes. The cell includes a cleaning assembly integral with the cell body, and the electrodes of the cell are integrated with a plunger reciprocably mounted within the cell body. In operating position, the electrodes are extended by actuation of the plunger into a thimble insert which, with the components provided by the thimble insert provide the essential components of an operative cell. The plunger, when the cell has become insensitive due to desensitization of the electrolyte, can be withdrawn from the thimble insert, aligned with the cleaning apparatus, the electrodes cleaned and a fresh electrolyte installed upon the electrodes, and the electrodes returned to operative position by mere reactuation of the plunger. The invention also provides a process for maintaining a dry orthophosphoric acid electrolyte in its dry state, as opposed to its metaphosphoric or anhydride states, to increase the period of sensitivity of an electrolytic cell as employed in moisture analyzers, particularly that described herein.
