<p><P>PROBLEM TO BE SOLVED: To provide an analytical method capable of separating deposits etc. (especially of a size of 1μm or below) present in a metal sample without any loss and accurately analyzing the deposits etc. for every size. <P>SOLUTION: (1) The metal sample is electrolyzed. (2) A deposit and/or an inclusion adhering to a remaining part of the metal sample after electrolyzation and a deposit and/or an inclusion contained in an electrolytic solution after the electrolyzation are both filtered out and collected. (3) Filtered and collected deposits and/or inclusions are immersed in a solution having dispersiveness and separated into the dispersive solution. (4) The deposits and/or inclusions separated into the dispersive solution are analyzed. In (2), the deposit and or the inclusion adhering to the remaining part of the metal sample after the electrolyzation are immersed in a solution for collection and separated into the solution for collection, and the solution for collection is filtered by a filter A for collection. The electrolytic solution after the electrolyzation is filtered by a filter B for collection. In (3), the filter A for collection and the filter B for collection are immersed in the solution having dispersiveness. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
