Oxygen gas sensing technologies: A comprehensive review

Abstract

Different oxygen gas sensing technologies, i.e., potentiometric, amperometric, paramagnetic and tunable diode laser spectroscopy (TDLS) are reviewed in details. Special attention is given to the theoretical aspects and operation basics of the technologies, application limits and analyzers or system requirements. A comprehensive technologies review is supported with the latest developments trends especially on the potentiometric zirconia and tunable diode laser analyzers.
