Abstract
Accurate knowledge of the stoichiometry of single crystals has been one of the major experimental problems in cuprate superconductivity, particularly when studying dopants or nonstoichiometric systems such as Bi-Sr-Ca-Cu-O. In this paper it is shown that Electron Probe Microanalysis (EPMA) can be used to perform non-destructive stoichiometric analyses of all the elements in single crystals of cuprate superconductors to an accuracy of approximately 2%. The paper gives a detailed description of the special methods that must be employed to obtain this accuracy.
