Abstract: An electrochemical system includes a first electrode for sensing a fluid sample to be analyzed and a reference electrode. The reference electrode is disposed in electrolyte and a membrane separates the electrolyte from the fluid sample. The membrane has a multiplicity of parallel passages, the width of each passage being less than one-half micron, such that the passages provide a multiplicity of similar ionic junctions between the electrolyte and the fluid sample.
