Abstract: Methods, apparatuses and systems for providing gas detecting apparatuses (e.g., electrochemical detectors) are disclosed herein. An example gas detecting apparatus may comprise a sensing component comprising: a first sensing electrode configured to generate a first concentration level indication associated with a first portion of a sample gaseous substance disposed within the sensing component; and a second sensing electrode operatively coupled to a filtering element that is configured to absorb at least one substance from the sample gaseous substance, wherein the second sensing electrode is configured to generate a second concentration level indication associated with a second portion of the sample gaseous substance.
