The uniqueness and limited amounts of forensic samples and samples from objects of cultural heritage together with the complexity of their composition requires the application of a wide range of micro-analytical methods, which are non-destructive to the samples, because these must be preserved for potential late revision. Laboratory powder X-ray micro-diffraction (micro-XRD) is a very effective non-destructive technique for direct phase analysis of samples smaller than 1 mm containing crystal… Expand
Combining grazing incidence X-rays and micro-diffraction for qualitative phase identification in forensic powdered micro-samples.
TLDR
A new data acquisition technique, based on the combination of two known diffraction methods, could be a powerful tool for studying samples outside of forensic sciences such as nanomaterials, medicine, or any other field where the sample quantity is extremely small, without the need to transport evidence and travel to external facilities with higher analytical performance.

Non-destructive micro-analytical differentiation of copper pigments in paint layers of works of art using laboratory-based techniques.
TLDR
An analytical procedure for unambiguous determination of both mineral-type (azurite, malachite, posnjakite, atacamite, etc.) and verdigris-type copper pigments in the paint layers is presented, including light microscopy under VIS and UV light, electron microscopy with elemental microanalysis, Fourier transformed infrared micro-spectroscopy, and X-ray powder micro-diffraction.
