Abstract: A process fluid connector for a single-use process fluid sensing system is provided. The process fluid connector includes a pair of process fluid connections, each process fluid connection being configured to couple to a cooperative process fluid coupling. A process fluid conduit section is operably coupled to each of the process fluid connections. A sensor attachment port is coupled to the process fluid conduit section and is configured to receive and mount a process fluid sensor. A retractable fluid chamber is coupled to the process fluid conduit section and configured to provides wet storage for sensing component(s) of the process fluid sensor. A process fluid sensing system using the process fluid connector is also provided.

Abstract: A single-use electrochemical analytical sensor is provided. The sensor includes a sensing electrode configured to contact process fluid and a reference chamber containing an electrolyte. A reference electrode is disposed in the electrolyte. A reference junction is configured to contact the process fluid and is further configured to generate a flow of electrolyte into the process fluid. The reference chamber is configured to be stored in a depressurized state and then pressurized prior to operation. A method of operating a single-use electrochemical sensor is also provided.
