Electrochemical cell
Abstract
Abstract THE DISCLOSURE RELATES TO AN IMPROVEMENT IN AN ELECTROCHEMICAL CELL FOR USE IN ION POTENTIAL MEASUREMENTS OF SOLUTIONS THE CELL CONTAINS A SENSING ELECTRODE, A REFERENCE ELECTRODE, AND AN EXTERNAL ELECTROLYTE COMPRISING THE SOLUTION TO BE TESTED. AT LEAST ONE ELECTRODE COMPRISES AN INTERNAL HALF CELLS SUPPORTED IN A CONTAINER OF NONCONDUCTIVE MATERIAL CONTAINING A SALT SOLTUION, AN INTERNAL ELECTROLYTE AND A LIQUID JUNCTION STRUCTURE OF AN ION PERMEABLE MATERIAL. THE IMPROVEMENT COMPRISES A SURFACTANT ADDED TO THE CELL SO THAT THE CONTACT ANGLE BETWEEN THE SOLUTION AND THE LIQUID JUNCTION STRUCTURE IS LESS THAN ABOUT 90*. AS A RESULT THE LIQUID JUNCTION STRUCTURE IS MADE MORE PERMEBLE TO WATER MOLECULES. AN IMPROVED ELECTROCHEMICAL ELECTRODE FOR USE IN ION POTENIAL MEASUREMENTS OF SOLUTIONS IS ALSO DISCLOSED.
