The subject is focused on the interpretation of chromatographic and mass spectrometric data generated within analysis of various food components. 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) non-targeted screening in food analysis; (v) techniques for the quantification of analytes and their confirmation; (vi) statistical methods for the data processing and interpretation (multivariate analysis).
Aim of the course -
Last update: TAJ323 (12.12.2013)

Students will be able to:

  • Use separation techniques (GC and LC) in combination with mass spectrometric detection 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 its isotopic profile, calculate formula and number of double-bonds.
  • Qualitatively analyse LC-MS and GC-MS data, apply 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.
