Annotation -
The course focuses on analytical procedures using chromatographic and, in particular, mass spectrometric methods for the determination of organic compounds in complex matrices. These are mainly analyses in the field of food quality and safety and procedures used in forensic analysis. The main emphasis in the course is placed on ensuring the quality of measured data and the rules for their interpretation. The following thematic areas are presented: (i) chromatographic techniques for connection with mass spectrometry; (ii) mass spectrometry - ionization techniques, mass analyzers and detectors, ion mobility (iii) interpretation of mass spectra and automated annotation; (iv) targeted analysis - legislation, confirmation criteria, quantification, matrix effects; (v) targeted screening and untargeted analysis, statistical data processing, multivariate analysis.

Teaching methods -

In the course, students gain basic knowledge about the combination of chromatography techniques with mass spectrometry, various approaches to data acquisition and processing, and the possibilities of using contemporary software tools. Students learn in the form of lectures with included practical aspects. Methods are used during teaching to verify understanding of the subject matter, most often in the form of interactive tests during the lecture.

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.
