Instrumental Techniques in Environment

This course is part of the programme:
Master’s study programme Environment (2nd level)

Objectives and competences

The aim of the course is to deepen the students’ knowledge of and acquire practical experience in instrumental methods of chemical analysis and to acquaint students with practical work on actual complex problems and with the equipment and its optimization that is essential for determining the state of the environment and in contemporary research of environmental phenomena.

Prerequisites

Prerequisite adequate knowledge of chemistry, environmental chemistry and physics, as well as of certain chapters of mathematics, above all of functions and derivatives, and statistics. Completed exam in Instrumental Methods of Analysis at 1 st. cycle program Environment, or equivalent exam elsewhere.

Content (Syllabus outline)

  • Sample preparation: methods of sample preparation, pre-concentration, extractions
  • Measurement uncertainties, statistical analysis: statisticl comporison of methods and results, detecting errors
  • Spectroscopic methods:

- Absorption spectrometry (UV-Vis, NIR and FTIR spectrometry, AAS, ET-AAS)

- Emission spectrometry (fluorescence, luminescence, XRF)

- Mass spectrometry, quadrupolle detectors, ion trap

  • Electrochemical methods:

- Microelectrodes

- Voltametric methods (stripping polarography, cyclic voltametry)

  • Separation methods:

- Gas and liquid chromatography (optimization of separation conditions)

- Hyphenated techniques (HLC-MS, GC-MS, MSn techniques)

- Capillary electrophoresis

  • Radioanalytical methods: neutron activation analysis
  • Biochemical methods: radioimmunological tests, biosensors
  • Automated methods for continuous measurements:
