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.
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.

Micro-analytical evidence of origin and degradation of copper pigments found in Bohemian Gothic murals
A new, until now unpublished, type of copper pigment—cumengeite, Pb21Cu20Cl42(OH)40—used as a blue pigment on a sacral wall painting in the Czech Republic was found by means of micro-XRD, in a good agreement with the results of laboratory experiments, which also show that oxalic acid accelerates the corrosion of Cu pigments.
