A STUDY OF QUANTITATIVE ELECTROCHEMICAL ANALYSIS THROUGH A SPECTROELLIPSOMETRIC TECHNIQUE WITH A NEW FUNCTION

Ellipsometry with a new function the 'Optical tracking rate' (Vop), us ed to analyze electrochemical reactions as suggested by the authors, i s described briefly. A series of applications of this new approach for qualitative and quantitative analysis including so-called potential s canning ellipsometry and stripping ellipsometry is introduced and disc ussed in this article. The experimental results indicate that strippin g ellipsometry for quantitative analysis has a higher sensitivity and accuracy than the electrochemical method.
