Description
Prof. Kamil Kamiński
An analytical chemist serving as a forensic expert is responsible for the reliable examination of evidence using advanced instrumental analytical methods. Their role involves not only the identification and comparison of trace materials or chemical substances, but also the proper interpretation of results in the context of the forensic question, taking into account measurement uncertainty and methodological limitations. The expert’s opinion becomes a key component in the decision-making process of law enforcement and the judicial system. During the lecture, students will become familiar with: the basic concepts and objectives of applying instrumental analytical methods in physicochemical forensic examinations; instrumental analytical methods used in forensic laboratories for the analysis of evidential samples, with particular emphasis on the problem of trace evidence analysis, by a) scanning electron microscopy coupled with X-ray spectroscopy (SEM-EDX), b) X-ray fluorescence spectrometry (XRF, µ-XRF), c) microspectrophotometry in the UV-VIS range (MSP), d) infrared spectroscopy (FTIR), e) Raman spectroscopy, f) chromatographic methods; the fundamental issues related to the interpretation of the evidential value of various types of data obtained in forensic laboratories, with particular emphasis on the likelihood ratio test.
