Abstract

See full text

An amperometric sensor includes a sensor body having a distal end and an interior containing an electrolytic fill solution. A porous membrane is disposed proximate the distal end to allow diffusion of molecules or ions of interest. A working electrode is disposed within the sensor body proximate the membrane. A counter electrode is disposed to conduct current between the counter electrode and the working electrode. The counter electrode is physically isolated from the electrolytic fill solution. A method of measuring a concentration of the molecules or ions of interest is also provided.
