Chemical detector utilizing an electrolytic gel
First Claim
1. An electrolytic cell for the detection of hydrazine in water comprising an elongated hollow cylindrical member formed of a porous insulating material, insulating means for supporting said member in said water, a platinum electrode wound about the outer side of said member and having a lead wire extending therefrom, a silver electrode within said member and having a lead wire extending therefrom, an electrolytic gel containing silver oxide at least partially filling said member and enveloping said silver electrode and indicating means connected between said lead wires, said indicating means responding to the current flowing between said electrodes when hydrazine is present in the water.

Abstract
A detector for reducing and oxidizing agents carried by fluids which detector includes an elongated exposed porous member having an opening extending therethrough, an electrolyte gel containing a metal salt filling said opening, a first metal electrode extending through said gel and a metal electrode on the outer side of said porous member, the porous member and electrode upon being placed in the path of the fluid will cause a current to be developed between the electrodes which is proportional to the amount of chemical in said fluid. The detector is especially useful for the detection of hydrazine in boiler feed water.
