First Claim
Patent Images
1. A polarographic cell comprising a sensor electrode and a reference electrode,said reference electrode being a silver/silver chloride electrode comprising a ring of silver metal in contact with a concentric ring of silver chloride that has a thickness of at least 25μ
- , said reference electrode being capable of serving as a counter electrode to complete an electric circuit with said sensor electrode, a sufficient quantity of silver chloride being present so that 2,000 assays can be performed where the current used in each assay is 5 nanoamps and the length of each assay is 60 seconds.wherein during the operation of said electrode assembly, current flows through said electric circuit and the silver ion from said silver chloride is reduced to silver metal, said cell being connected to means for measuring said current, andwherein said polarographic cell lacks a third electrode.
