<P>PROBLEM TO BE SOLVED: To provide a scanning probe microscope capable of analyzing ions eluted into a solution from a sample, and a method for detecting the ions in the solution using the scanning prove microscope. <P>SOLUTION: A scanning prove microscope having an electrochemical cell 5 in which a sample 1, a reference electrode 2, a counter electrode 3, and a prove 4 are disposed in a solution, for measuring a rugged shape of a sample surface using the prove 4, comprises: prove potential control means (7, 8 and 100) for variably controlling electric potential of the prove 4 with respect to the reference electrode 2; and current detection means for detecting a prove current flowing in the prove by an electrochemical reaction between the prove 4 and the counter electrode 3 under variably controlled prove potential. The scanning prove microscope identifies a potential range in which ions existing in the solution are caught by the probe 4 to indicate an oxidation or reduction reaction, from the probe potential and the probe current, to identify and quantitate the ions in the solution. <P>COPYRIGHT: (C)2013,JPO&INPIT |
