The subject is focused on the analytical procedures employing chromatographic and mass spectrometric techniques for the analysis of organic compounds in complex matrices. The main discussed applications are food quality and safety, environmental and forensic analysis. The following topics are discussed: (i) connection of chromatographic and mass-spectrometric techniques; (ii) interpretation of mass spectra; (iii) software for analyte identification and data processing; (iv) targeted screening in food and analysis; (v) techniques for the quantification of analytes and their confirmation; (vi) statistical methods for the data processing and interpretation (multivariate analysis).

The basis of the exam is a written test, consisting of five thematic areas (TO). A minimum of 40% points must be obtained for each TO. A minimum of 50% points must be obtained for the written test in total. If this is not met, the exam is graded F. Last update: Stránská Milena (22.12.2025)
