Annotation
Last update: RNDr. Jakub Hraníček, Ph.D. (13.10.2020)
The course is taught in English for Erasmus students.

The course of laboratory practice in analytical chemistry trains experimental skills in classical and instrumental analytical techniques. The course ends through a written test in calculations and a practical exam in analysis of unknown sample.

During epidemiological measures: This subject is taught only in the face-to-face form if it is possible.

Requirements to the exam
Last update: doc. RNDr. Karel Nesměrák, Ph.D. (28.10.2019)

In order to obtain the credit from the basic course in analytical chemistry, students must successfully complete all practical tasks with an average grade of less than 2.5, pass the final written test and successfully carry out the final analysis of the practical sample.

Syllabus
