摘要
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.
