Claim Text:
1. A method of determining leveler concentration in a test solution, comprising: (a) providing an electrode having a metal surface; (b) exposing the electrode to a pre-acceleration solution comprising at least one accelerator compound and allowing the surface of the electrode to become substantially saturated with the at least one accelerator compound before removing the electrode from the pre-acceleration solution; (c) exposing the substantially saturated electrode to the test solution and measuring an electrochemical response while plating the substantially saturated electrode in the test solution, the test solution having an unknown concentration of leveler; and (d) determining the concentration of leveler in the test solution by comparing the electrochemical response obtained in operation (c) to a model relating leveler concentration to known electrochemical responses.
