Scope

This International Standard specifies a method for evaluating the repeatability and constancy of the intensity scale of X‑ray photoelectron spectrometers, for general analytical purposes, using unmonochromated Al or Mg X‑rays(Al Kα or Mg Kα) or monochromated Al X‑rays(Al Kα). It is only applicable to instruments that incorporate an ion gun for sputter cleaning. It is not intended to be a calibration of the intensity/energy response function. That calibration may be made using ISO 5861,[18] by a method recommended by the instrument manufacturer, or other documented approach. The present procedure provides data to evaluate and confirm the accuracy with which the intensity/energy response function remains constant with instrument usage. Guidance is given on some of the instrument settings that may affect this constancy.
