The removal of iron corrosion products is considered necessary in textile conservation and it is usually undertaken by the application of chelating agents. The efficacy of the various chelating agents is not always known and therefore, non-destructive analytical methods are often used to assess their performance. In the present work, Energy Dispersive X-ray fluorescence (EDXRF) spectroscopy was used to determine iron in textile samples before and after cleaning. It was shown that EDXRF provides a simple, rapid, non-destructive technique to determine the efficiency of iron removal after conservation treatment in textiles.

Archaeological Objects

Coins are important archaeological objects that can provide useful information regarding preparation methodology and provenance. Their classification plays a fundamental role in dating historical events, in constructing trade routes and in establishing the welfare of population. Several Indian copper coins of different periods have been studied using Energy Dispersive X-ray Fluorescence (EDXRF) spectroscopic technique. The method is rapid, efficient, multi elemental and non-destructive in nature. Concentrations of the major and trace elements like Ca , Ti , V , Cr , Mn , Fe , Co , Ni , Cu , Zn , As and Pb have been estimated in these copper coins. In the present investigation, an attempt has been made to characterize some Indian copper coins of different periods using EDXRF technique.

Handheld portable energy-dispersive X-ray fluorescence (pXRF) spectrometry is used for non-destructive chemical characterization of archaeological ceramics. Portable XRF can provide adequate analytical sensitivity to discriminate geochemically distinct ceramic pastes, and to identify compositional clusters that correlate with data patterns acquired by NAA or other high sensitivity techniques. However, successful non-destructive analysis of unprepared inhomogeneous ceramic samples requires matrix-defined scientific protocols to control matrix effects which reduce the sensitivity and precision of the instrumentation. Quantification of the measured fluorescence intensities into absolute concentration values and detection of light elements is encumbered by the lack of matrix matched calibration and proper vacuum facilities. Nevertheless, semi-quantitative values for a limited range of high Z elements can be generated. Unstandardized results are difficult to validate by others, and decreased analytical resolution of non-destructive surface analysis may disadvantage site-specific sourcing, jeopardize correct group assignments, and lead to under-interpretation of ceramic craft and production systems.

The majority of expert examination in forensic science is concerned with comparison, determination, and description of diversified samples. X-ray diffraction (powdered and/or single crystal) is bringing big benefits and analytical possibilities into forensic expert work, which are not easily provided by other methods. XRD methods are used in combination with other analytical methods (SEM with EDS/WDS, micro XRF, optical microscopy, FTIR, etc.).Importance of XRD phase analysis in forensic science lies namely in: analysis of relatively small-volume samples, relatively non-destructive, exact phase analysis, quantitative analysis (in majority of cases). And method is conclusive for a court.

ABSTRACTThe first preliminary results from a novel spectrometer for elementally-specific measurements of magnetic surfaces and ultrathin films are presented here. The key measurements are based upon spin-resolving and photon-dichroic photoelectron spectroscopy. True spinresolution is achieved by the use of a Mini-Mott detection scheme. The photon-dichroic measurements include the variant magnetic x-ray linear dichroism (MXLD). Both a multi-channel, energy dispersive collection scheme as well as the spin-detecting Mini-Mott apparatus are used in data collection. The [Spin Spectrometer] is based at the Spectromicroscopy Facility (Beamline7)at the Advanced Light Source.
