Portable energy dispersive X-ray fluorescence spectrometry and PIXE for elemental quantification of historical paper documents

Abstract

We have used a portable energy dispersive X-ray fluorescence spectrometer based on a silicon drift detector for elemental quantification of a historical paper document. Quantitative calculations were carried out using the WinAxil software package. In order to minimize matrix effects and to accurately reflect the conditions under which quantification is usually performed, the fundamental parameters package with a known paper samples was used. Reference values for paper samples were obtained through a set of a particle induced X-ray emission techniques.
