Abstract
The quantitative analysis of strong reducing agents is determined by measuring the electrode potential created by an oxidation-reduction reaction occurring at an electrode assembly having an active electrode formed from a mixture of finely divided platinum and platinum oxide. The electrode assembly has been found to be particularly sensitive in determining the concentration of hydrazine and hydrazine containing compounds.

A method for determining the concentration of a reducing agent in a fluid, which is capable of reducing platinum oxide to platinum, comprising the steps of fabricating an active electrode from a mixture of platinum and platinum oxide constructed and arranged to retain its structural integrity during use, placing said active electrode proximate to a counter-electrode, bringing said electrodes in contact with said reducing agent in said fluid, and measuring the electrode potential created from an oxidation-reduction reaction occurring between said electrodes and said reducing agent.
A method for determining the concentration of a reducing agent in a fluid, which is capable of reducing platinum oxide to platinum, comprising the steps of fabricating an active electrode from a mixture of platinum sponge and platinum oxide in the weight ratio of from 1/1-20/1 and constructed and arranged to retain its structural integrity during use, placing said active electrode adjacent a counter-electrode, bringing said electrodes in contact with said reducing agent in said fluid, measuring the electrode potential created from an oxidation-reduction reaction occurring between said reducing agent and said electrodes to determine the concentration of said reducing agent in said fluid.
