Annotation -
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).

Requirements to the exam -

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.

Learning outcomes -

Students will be able to:

  • Choose right separation technique (GC or LC) in combination with particular type of mass analyser for different analytical tasks. They will understand the basic characteristics of different ionization techniques and mass spectrometers.
  • Analyse mass spectrum, find the molecular ion and analyse isotopic profile, calculate formula of simple moleule from an isotopic profile and calulate a number of double-bonds.
  • Qualitatively analyse LC-MS and GC-MS data, apply correct smoothing algorithms, spectral deconvolution, to use mass spectra libraries and retention indexes for the identification of analytes.
  • Quantify obtained data, confirm results, use different calibration approaches (external calibration cuve, method of standard addition, internal standards, isotopic dilution) in LC-MS and GC-MS.
  • Apply different chemometric tools for the data structure and get the maximum of information from recorded data.
