advanced knowledge of english to extent required in the study
Course Enrolment Limitations
The course is also offered to the students of the fields other than those the course is directly associated with.
fields of study / plans the course is directly associated with
Course objectives
the main objective of the course is to acquaint students with separation methods based on equilibrium separation between two phases.
another objective of the course is to provide this knowledge in english in order to improve students' language skills
Learning outcomes
at the end of the course students should be able:
to manage general principles of analytical separation and its description
to manage principles of equilibrium separation between two phases
to describe and explain basic separation modes using the following phase systems - liquid-liquid, solid-liquid, solid-gas, liquid-gas
to describe and explain principles and practical aspects of liquid and gas chromatography.
Syllabus
  • 1. introduction to separation: separation of two ideally miscible compounds, separation limits, separation methods classification – preparative, analytical, basic principles of separation – molecular equilibrium, intermolecular interactions, entropy.
  • 2. extraction: description of extraction equilibria in system liquid-liquid and in system liquid-solid; choice of extraction system, carry-out of extraction, influence of analyte-solvent interaction, repeated extraction
  • 3. preanalytical sample preparation: CCE (counter-current extraction), SFE (supercritical fluid extraction); ASE (accelerated solvent extraction); MAE (microwave assisted extraction), SPE (solid phase extraction); SPME (solid phase microextraction), HSE (head-space extraction)
  • 4. analytical separation: chromatography, basic techniques (frontal, displacement, elution), theoretical principles – column equilibrium, physico-chemical description of processes on LC, kinetic and thermodynamic aspects of separation.
  • 5. study and description of separation; quantitative relations between structure and selectivity in regard to retention; liquid chromatography (LC) – history, theoretical ground; classification of basic separation mechanisms in LC (LLC, LSC, IEC), LC arrangement: mobile phase delivery, elution and elution force (isocratic and gradient); injection devices; separation column, types of stationary phases (particle, monolithic, on-chip), overview of sorbents;
  • 6. detectors photometric (DAD), refractometric, fluorescence, amperometric, conductivity, light-scattering, mass spectrometric, derivatisation and sample collection. description and evaluation of separation results: defining the chromatographic system, analytical information in chromatogram (qualitative, quantitative); precision, accuracy, limits of analysis (MDL, LOD, LOQ); evaluation of separation efficiency, testing of the system and its “good” behaviour;
  • 7. basic LC modes: CCC (counter-current chromatography), NP-HPLC (normal phase liquid chromatography), RP-HPLC (reverse phase liquid chromatography), TLC (thin-layer chromatography, HPTLC 2D TLC), ultra-high performance chromatography, high temperature liquid chromatography, elevated-temperature ultra-high performance chromatography, hydrophilic interaction chromatography (HILIC), ERLIC, hydrophobic interaction chromatography (HIC),
  • 8. IEC (ion exchange chromatography) – principles and carry-out, IXC (ion exclusion chromatography), chromatofocusation; affinity chromatography – principles, IMAC (immobilised-metal affinity chromatography); SFC (supercritical fluid chromatography); PC (perfusion chromatography);
  • 9. multi-dimensional chromatography: interface and principles; hyphenated separation techniques; preparative chromatography: methods (system scale-up, system overloading), fraction collection,
  • 10. gas chromatography (GC): history, differences between LC and GC (isotherms, gas compressibility, retention quantities), GC arrangement, mobile phase delivery; injection device (split, splitless); separation column, stationary phase types (WCOT, FSOT, SCOT, PLOT), column thermostat, detectors (flame ionisation, chemiluminescence, mass spectrometric detectors, etc.), GC system definition, GC evaluation and testing.

Teaching methods
the lecture is based on ppt presentation and its explication. presentations themselves will be available in both, czech & english, as study materials (black-and-white printable pdf with high resolution and restricted access rights). it is recommended to attend the lecture, because of the explication, which significantly extends the presentation, and because there are no available textbooks in czech language covering certain parts of the subject.
during the course, students will be given voluntary, ungraded, but corrected, time-saving tasks to consolidate the acquired knowledge.
Assessment methods
the oral examination will be conducted in czech, eventually, when agreed, in english; students are required to understand and to be familiar with the principles and their applications. the examination consists of three basic questions, which would be during the examination expanded to let the student demonstrate the extent of topic understanding.
