Commercial surface analysis systems have been available since around 1970 (1). Most of the early instruments were dedicated to longer-term fundamental research, even if they were located at industrial research centers. However. since the latter part of the 1980s, the most popular surface analytical techniques. Auger electron spectroscopy (AES), secondary-ion mass spectrometry (SIMS) and X-ray photoelectron spectroscopy (XPS), have gained a greater level of acceptance in industry due to their improved reliability. Surface analysis is now routinely used to solve complex industrial problem.s in both research and quality assurance environments. It has been specifically the move toward the use of these techniques in quality-assurance-type applications that has started to force the development of national/international documentary standards in order to formalize the methods of application of the techniques.
