Abstract

The major problem in X-ray photoelectron spectroscopy of polymeric and other insulating materials is that of ``charge neutralisation'' or `` charge compensation''. Due to variable potentials on the surface of the investigated specimen broadening of peaks, or even multiple peaks, are observed. Various methods are applied to achieve the charge compensation. The AXIS series of instruments provide a secure and reliable charge compensation method, which uses the characteristic properties of the magnetic lens. The system enables confident determination and use of small binding energy shifts in both spectroscopy and imaging.
