Training of chemistry students in the Institute of Forensic Research Janina Ziba-Palus Lecture: Chemistry in criminslistics 30 h Forensic Toxicology - 30 h Laboratory courses (each 5 h) examination of paint fibres identifacation examination of glass GSR examination examination of ink drugs inorganic poisons Seminar (1 h) - before each laboratory taining Forensic Chemistry Participants: students of chemistry (4th year of study) group consist of people during lab training students are divided into two groups performing practical exercises using analytical equipment (microscopes, spectrometers) and preparing reports basing on the obtained results they elaborate mini projects- research and literature study in the field of forensic chemistry 4 th year, II semester they elaborate master thesis during two semesters - 5 th year: - on identification of car paints by the use of IR, SEM/EDX, Py-GC/MS or Vis spectrometry - on examination of GSR by the use of SEM/EDX - on differentiation of glass fragments using SEM/EDX, RI - on identification of fibres using optical microscopy - on organic and inorganic poisons identification summer practice is performed two weeks sometimes they are employed within research project financed by Polish government and EU Moreover, students of Strathclyde University (Glasgow) prepare their master thesis 3 months students from Fachschule in Instein (Germany) practical training during 5 months Paints Optical microscopy: - morphology - layer structure - colour - pigments IR spectroscopy SEM/EDX IR spectroscopy chemical content of each layer Fibres Optical microscopy, SEM - morphology Vis spectroscopy comparison of fibre colour IR spectroscopy identification of polymer (type of fibre) Glass Grim 2 RI measurement SEM/EDX quantitative elemental analysis in order to classify and compare of glass fragments using chemometric methods GSR Metal particles Metal particles: - spherical shape - several microns in diameter - specific composition SEM/EDX Inks absorption in white light absorption in IR light VSC Raman spectroscopy Extraction solution Pyridine 1. Isolation of writing materials from paper Three types of elution solutions Butanol : ethanol : Distilled water : acetic acid Ethyl acetate : ethanol : distilled water Ethyl acetate : propanol : distilled water : acetic acid 2. Developing of chromatograms Observation of chromatograms in UV/VIS light 3. Interpretation of chromatograms black ink acid blue blue gel glicerine styrene IR spectroscopy
