Description
An analytical method that uses a focused beam of x-ray photons to ionize inner core electrons in the sample. These electrons are ejected and measured to identify the elements in the surface of the sample. Information is also obtained on the chemical bonding state of each element. Electron spectroscopy for chemical analysis (ESCA) is a surface analysis technique in which only the upper monolayers of the surface are analyzed. The analysis area is approximately 1 square millimeter.
