Solid state pH sensing continuous flow system

A continuous flow pH monitoring system, comprising:

• a solid state pH sensor having an analyte sensitive material (ASM) covalently bound to a polymer backbone, wherein the ASM comprises at least one of a quinone, dihydroxy anthraquinone, or an anthraquinone derivative, and wherein the polymer backbone is poly(vinyl alcohol);
• a pH sensor housing comprising:
• an outer top surface comprising a threaded opening;
• an outer bottom surface opposite the outer top surface;
• a sidewall comprising an outer sidewall surface and an inner sidewall surface, said inner sidewall surface in fluid communication with the outer top surface via the threaded opening;
• an inner bottom surface, said inner bottom surface and said inner sidewall surface defining a fluid pathway;
• an inlet port positioned in the sidewall in proximity to, and spaced apart from, the inner bottom surface and in fluid communication with the fluid pathway;
• and
• an outlet port positioned in the sidewall in proximity to the threaded opening and in fluid communication with the fluid pathway, such that a distance between the outlet port and the inner bottom surface is greater than a distance between the inlet port and the inner bottom surface;
• a pH probe adapter threadedly coupled to the threaded opening of the pH sensor housing, the pH probe adapter further comprising a central opening configured to selectively receive the solid state pH sensor such that a distal tip of the ASM of the solid state pH sensor is positioned between the inner bottom surface and the inlet port;
• a sealing member housed within the central opening of the pH probe adapter and interposed between the solid state pH sensor and the pH probe adapter to provide a fluid tight seal therebetween;
• and
• a computer processor operably connected to the solid state pH sensor and configured to receive data from the solid state pH sensor.
