This course trains the participants in a wide range of methods used for analysis of trace metals in liquid and solid samples. Attention is given to both sample preparation options and the working principles of different analytical instruments that can be used, mostly focused on atomic spectrometry techniques. Advantages and disadvantages of the different options are dealt with. At the end of the course, participants should be able to select the most appropriate method for a particular application and deal with difficulties that may arise when using a method (e.g., interferences). Analysis of total trace element concentrations as well as speciation analysis, i.e. assessment of the form of occurrence of the trace elements in the samples, are highlighted. Videolectures and reading assignments are alternated with theoretical and calculation exercises and short quizzes.
