Within this course, principles and key applications of modern isolation, separation and detection techniques commonly used in the field of studies / characterization of biologically active compounds. Special attention is paid to (i) application of basic and advanced extraction techniques; (ii) effective separation strategy realized by gas / liquid chromatography; (iii) presentation of various instrumental techniques with a special focus on mass spectrometry and its presentation in case studies. In the final phase of course, practical aspects together with problems to be solved in a qualified manner in practice are summarized.
Aim of the course -
Last update: TAJ323 (28.08.2013)

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.
  • Utilization of separation techniques (gas / liquid chromatography) coupled with mass spectrometric detection for analysis of complex mixtures of natural compounds.
  • Basic characteristics of various ionization techniques and mass analysers and their use for identification and quantification of analytes.
  • Application of non-target screening (metabolomic fingerprinting / profiling) followed by statistical processing of experimental data.
