Course objectives
main objectives of lecture: introduction into analytical separation methods; mastering their principles; acquainting with the wide scope of their contemporary implementation and utilisation; definition of terms pre-analytical separation, separations analytical and preparative; choice and optimisation of separation system, evaluation of its efficiency, with validation of separation method and evaluation of the separation results.
Syllabus

Teaching methods
the lecture is based on ppt presentation and its explication. presentation it-self will be available as a study material (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.
Assessment methods
oral examination; students are required to understand and be familiar with the principles and its applications. examination consists of three basic questions, which would be during the examination expanded to let the student demonstrate the extent of topic understanding.
Language of instruction
Czech
