Abstract:
A method for in-situ cleaning of electrodes the electrodes being mounted within an electrode housing, and having a surface in communication with a liquid to be measured comprising:providing a cleaning solvent to a solvent supply orifice via said electrode housing, said solvent supply orifice adjacent an electrode to be cleaned;causing a cleaning baffle having a solvent channel extending along a surface of the cleaning baffle directly facing the electrode and supply orifice to move be rotated from a first position adjacent the electrode to a second position covering the surface of the electrode wherein when the cleaning baffle is said first position, analysis of the liquid to be measured occurs, and when the cleaning baffle is in the second position, cleaning of said electrode occurs; anddirecting the cleaning solvent from the solvent supply orifice, across the surface of the of the electrode using the solvent channel, when the cleaning baffle is in the second position.
