Surface chemical analysis. X-ray photoelectron spectroscopy. Procedures for assessing the day-to-day performance of an X-ray photoelectron spectrometerWhat is this standard about? This document is designed to allow the user to assess, on a regular basis, several key parameters of an X ray photoelectron spectrometer. It is not intended to provide an exhaustive performance check, but instead provides a rapid set of tests that can be conducted frequently. Aspects of instrument behaviour covered by this document include the vacuum, measurements of spectra of conductive or non conductive test specimens
