Abstract

This international standard specifies a method for calibrating the binding energy scales of x-ray photoelectron spectrometers, for general analytical purposes, using unmonochromated Al or Mg x-rays or monochromated Al x-rays. It is only applicable to instruments that have an ion gun for sputtering cleaning. This international standard further specifies a method to establish a calibration schedule, to test for the binding energy scale linearity at one intermediate energy, to confirm the uncertainty of the scale calibration at one low and one high binding energy value, to correct for small drifts of that scale for a calibration level of 95%. This uncertainty includes contributions for behaviour observed in inter-laboratory studies but does not cover all the defects that could occur. This international standard is not applicable to instruments with binding energy scale errors that are significantly non-linear with energy, to instruments operated in the constant retardation ratio mode at retardation ratios of <10, to instruments with a spectrometer resolution worse than 1.5 eV or to instruments requiring tolorance limits ±0.03 eV or less. This international standard does not provide a full calibration check, which would confirm the energy measuredat each addressable point on the energy scale and would have to be performed in accordance with the manufacturer's recommended procedures.
