Claim Text:
1. A method for determining a salt concentration of a hydrocarbon fluid using a conductivity sensor and a hydrocarbon testing solution, the method comprising the steps of: introducing the hydrocarbon testing solution into the conductivity sensor, where the conductivity sensor comprises a working electrode, a counter electrode and a reference electrode, where the hydrocarbon testing solution comprises the hydrocarbon fluid, an electropolymerizable monomer and a non-aqueous solvent; inducing a range of potential across the hydrocarbon testing solution contained in the conductivity sensor, such that the hydrocarbon testing solution forms an exhausted hydrocarbon testing solution; detecting a range of electrical current associated with the range of potential induced using the conductivity sensor; and determining the salt concentration of the hydrocarbon fluid using the range of potential induced across the hydrocarbon testing solution and the range of electrical current detected by the conductivity sensor.
