Claim Text:
1. An electrodeposition system comprising: a plating apparatus; and, a plating solution analysis and dosing apparatus comprising: said controller causing said power source to turn off in order to establish and maintain said equilibrium potential, said controller causing said polarity-switching unit to electrically connect said first electrode to said negative terminal and said second electrode to said positive terminal so as to form a first electric circuit and further causing said power source to turn on and supply a first operating current to said first electric circuit in order to perform said first metal plating process, said first operating current causing said first metal to plate on said first electrode such that a first concentration of said first metal in said plating solution is decreased and such that a second concentration of said second metal in said plating solution remains constant, and said controller causing said polarity-switching unit to electrically connect said first electrode to said positive terminal and said second electrode to said negative terminal so as to form a second electric circuit and further causing said power source to turn on and supply a second operating current to said second electric circuit in order to perform said first metal de-plating process, said second operating current causing said first metal to de-plate from said first electrode such that said first concentration of said first metal in said plating solution is increased.
