Composition of Renaissance Paint Layers: Simultaneous Particle Induced X-ray Emission and Backscattering Spectrometry

Analytical Chemistry, 2009
Particle induced X-ray emission spectroscopy (PIXE) is now routinely used in the field of cultural heritage. Various setups have been developed to investigate the elemental composition of wood/canvas paintings or of cross-section samples. However, it is not possible to obtain information concerning the quantity of organic binder.

Comparison of Glass Fragments Using Particle‐Induced X‐Ray Emission (PIXE) Spectrometry*^,†

Journal of Forensic Sciences, 2011
Abstract:  A procedure has been developed to analyze the trace element concentrations in glass fragments using particle‐induced X‐ray emission (PIXE) spectrometry. This method involves using accelerated protons to excite inner‐shell electronic transitions of target atoms and recording the resultant X‐rays to characterize the trace element ...

Chemical State Information of Bulk Specimens Obtained by SEM-Based Soft-X-Ray Emission Spectrometry

Microscopy and Microanalysis, 2014
AbstractElectron-beam-induced soft-X-ray emission spectroscopy (SXES) that uses a grating spectrometer has been introduced to a conventional scanning electron microscope (SEM) for characterizing desired specimen areas of bulk materials. The spectrometer was designed as a grazing incidence flat-field optics by using aberration corrected (varied line ...

Quantification in grazing-emission X-ray fluorescence spectrometry

Spectrochimica Acta Part B: Atomic Spectroscopy, 1999
Abstract In grazing-emission X-ray fluorescence (GEXRF) spectrometry wavelength-dispersive detection can be applied. Much softer radiation and hence lighter elements than in total-reflection X-ray (TXRF) spectrometry can thus be detected. We used simulations to investigate methods of quantification of GEXRF results involving soft characteristic ...
