Application of electrochemical impedance spectroscopy (EIS) for in situ study of glass alteration

In situ continuous recording of glass alteration is a difficult experimental problem. In this paper, an electrochemical method is proposed for monitoring the concentrations of dissolved ions in the altering solution. This method was tested in a real case (alteration of a binary glass in water at room temperature). The possibility to measure local concentrations in the vicinity of the glass/solution interface is an interesting prospective of the method.
