On completion of the course the student shall be able to:
describe the chemistry utilised in different methods used to visualise fingerprints
describe the chemistry used indifferent methods to identify explosives
account for the principles for the instrumental techniques presented during the course
use spectroscopic techniques to investigate for example documents, bullets, tools
suggest and use appropriate methods for determination of fire accelerators
utilise multivariate methods to distinguish chemical traces as glass fragments, and other pigments
evaluate results obtained with different methods with respect to selectivity and sensitivity
Methods for the analysis of samples taken at fire scenes to find the cause of the fire. Fingerprint with different techniques will be illustrated. Methods to connect bullets to manufacturer and weapons are discussed. Identification of paper with spectroscopic techniques. Analysis of pigments from documents and samples from car accidents such as flakes from paint and glass fragments where identification by means of multivariate data analysis is discussed. Identification of tools from their steel composition. Methods to distinguish different explosives are demonstrated.
The course comprises lectures, laboratory sessions, seminars and if possible a study visit. A larger literature project is also included.
Written examination at the end of the course. For approval, passed laboratory course and passed project, presented orally and with a written report, are also required. Laboratory sessions that are part of the course and projects are marked to 6 credits.
