Abstract
Various embodiments described herein relate to methods, apparatuses, and systems for recovering gas sensors from silicone poisoning. In an example embodiment, a method of recovering a gas sensing apparatus from silicone poisoning is provided. The method includes exposing the gas sensing apparatus to a predetermined hydrogen concentration for a period of hydrogen exposure time. The predetermined hydrogen concentration breaks down the silicon oxide bonds formed on a catalytic bead of the gas sensing apparatus. The method also includes providing a methane concentration to the gas sensing apparatus for a period of methane exposure time. The method further includes determining that the gas sensing apparatus satisfies a predetermined calibration sensitivity based on the reaction of the gas sensing apparatus to the methane concentration.
