Abstract
Systems and methods are provided for determining ion concentration of a fluid downhole using a polymer matrix packaged in a cartridge. An example method can include disposing a cartridge within a flow path of a sensor. The cartridge includes a bracket; a retainer formed of a porous material having pores sized to allow a fluid to flow therethrough; and a substrate comprising a polymer matrix embedded with an ion-indicator, the substrate configured to interact with the fluid and to modify an optical characteristic of the substrate according to an ion concentration of the fluid. The method further includes illuminating the substrate; detecting a change in an optical characteristic of the substrate, the change indicative of the ion concentration of the fluid; and determining the ion concentration of the fluid.
