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.

Within the extent of the syllabus.

1 Introduction to the issue, classification of biologically active substances

2 General characteristics of the analytical procedure, performance characteristics and validation, basic steps in the analysis of biologically active substances of both natural and anthropogenic origin

3 Basic and advanced extraction techniques with a focus on their use in practice

4 Gas chromatography (theory, injection techniques, classification of capillary columns, influence of various parameters on the separation process, optimization of separation, two-dimensional GC, conventional detectors)

5 Liquid chromatography (theory, selection of chromatographic system, columns and classification of stationary phases, conventional detectors, optimization and influence of various parameters on the separation process)

6 Mass spectrometry (introduction and characterization of application potential, ionization techniques, mass analyzers, ion mobility, detection)

7 Analysis of volatile compounds, GC-MS (case studies)

8 Analysis of environmental contaminants by GC-MS (case studies)

9 Analysis of environmental contaminants by LC-MS (case studies)

10 Bioanalytical methods I (biosenzors and portable systems for food analysis)

11 Bioanalytical methods II (principles of biomolecular recognition)

12 Analysis of pesticides and mycotoxins

13 Analysis of vitamins and other important biologically active compounds

14 Presentation of individual students works, discussion, preparation for final test

Group at MS teams, where students will complete short tests online to verify their knowledge at the end of each teaching block. After the evaluation of the tests, the results will be discussed with the students and the most common mistakes will be explained.

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.
