| Outline of Final Research Achievements |
Recently, X-ray photoelectron spectroscopy (XPS) which intrinsically requires vacuum was applied by our research group for in situ analyses of surface chemical states at solid/liquid interfaces during electrochemical reactions. In order to utilize this technique for a time resolved analysis of surface chemical states in situ in real time, a detection system of our laboratory base XPS was modified by utilizing an oscilloscope with a fast processing unit as a feasibility study. As a result, peak intensities and total counts of input electrons were improved by about two times, which can significantly improve the sensitivity and decrease the acquisition time. Now, further improvement is under consideration by using an external signal amplifier.
