Experimental SamplesA total of 75 sheet glasses were provided by three 2016 © The Japan Society for Analytical Chemistry † To whom correspondence should be addressed. Science, Kashiwa, Japan In this study, 3 automobile window glass manufacturers were identified based on refractive index, XRF, and XAFS analyses. The samples were classified into the corresponding groups using XRF, which should be the first step for identification. Samples having different manufacturing times showed differences in the refractive index. Based on XAFS, the amplitude of the EXAFS spectra and the intensities of Fourier transforms differed between manufacturers. In the scheme for manufacturer identification proposed in this study, performing XRF and refractive index studies is the first step. The concentrations of CeO2, MgO, Al2O3, and K2O allowed us to distinguish among manufacturers. Secondly, for samples containing cerium, we discriminated between manufacturer based on the amplitude of the EXAFS spectra and the intensities of Fourier transforms. As a result, the manufacturers of the 75 samples used in this study were multilaterally identified.

“…Trace and ultratrace elemental analysis by ICP-MS has also been used in many forensic analyses to determine if samples are similar to or distinguishable from one another. This technique has been used to compare various samples such as steel and glass (27), including float (36), container (37), sheet (38), and automotive (39) glass, for forensic analysis. Unfortunately, analysis of solid samples by ICP-MS requires dissolution of the sample into an aqueous solution.…”

This review gives an overview of the literature on reference materials of geochemical and environmental interest for the two‐year period 2008–2009. Reference materials play an increasingly important role in all fields of geoanalytical research. This is demonstrated by the large number of publications containing data on reference materials. Although many reference materials exist, there is still a great need for certified samples, so‐called delta zero materials for stable isotopic work and homogeneous microanalytical reference materials. This review focuses on six topics: developments of certification processes of reference materials mainly postulated in ISO guidelines and the IAG protocol, new developments of the GeoReM database, investigations of powdered rock reference materials, Chinese reference materials published in Chinese journals, microanalytical reference materials and isotopic reference materials.
