Abstract
Embodiments relate generally to systems and methods for preventing reaction between a sealing material (epoxy) and an electrolyte material within a carbon monoxide (or other gas) sensor. In general, the electrochemical sensor disclosed herein comprises a gas diffusion working electrode, a counter electrode, and optionally, a reference electrode. Each electrode is in contact with an aqueous electrolyte. The gas sensor may comprise a tab located proximate to gaps in the housing of the sensor, wherein the tab prevents any sealing material that fills the gaps from entering the interior of the housing. In some embodiments, the tab may be attached to a counter electrode. In some embodiments, the housing may comprise a slot located about the gaps, wherein the tab fits into the slot of the housing.
