Students will be able to understand:

• How to make a qualified choice of suitable sample preparation strategy (i.e. extraction and clean-up technique) for determination of target analytes.

• Principle and description of chromatographic techniques (gas or liquid chromatography) for the analysis of complex mixtures of biologically active compounds.

• Characterization of mass spectrometry (ionization techniques, mass analyzers) and its use in conjunction with chromatography for identification and quantification of analytes.

• Application of non-target screening (metabolomic fingerprinting / profiling) followed by statistical processing of experimental data.

To obtain the credit, it is necessary to prepare a group project (3-4 students) in the form of a presentation, which summarizes several case studies in the analysis of a selected group of biologically active substances. The award of credit is a necessary condition for passing the exam, which consists of a written part and possibly an oral exam.
