Abstract: A process analytic instrument (40) includes a measurement cell (60) and an analyzer circuit (50). The measurement cell (60) includes a solid state electrochemical oxygen sensor configured for exposure to a process gas. The analyzer circuit (50) is coupled to the solid state electrochemical sensor to measure an electrical parameter of the solid state electrochemical sensor and provide an output indicative of oxygen in the process gas. A DC bias circuit (130) is configured to selectably bias the solid state electrochemical oxygen sensor with a direct current when the solid state electrochemical sensor is in a reducing environment.

Abstract: A device for sensing a concentration of a combustible specie of interest (10, 20, 30, 50, 60) and a process analytic system (300) employing such sensors (10, 20, 30, 50, 60) are provided. The sensors (10, 20, 30, 50, 60) generally include a treatment or material that is adapted to increase the resistance of certain portions of the sensors (10, 20, 30, 50, 60) to exposure to sulfur. In one aspect, an improved sulfur-resistant process analytic system (300) includes a probe (302) with one or more sulfur-resistant sensors (10, 20, 30, 50, 60) therein coupled to a controller (308), a thermal control module (304), and a source of blowback gas (306).
