Pravidla hodnocení a ukončení předmětu

Course credit is awarded for 100% attendance at seminars (any absence must be properly apologized). Credit may be obtained for successful completing of three partial written tests during the semester (ie getting at least 6 points out of 10 possible). In case of failure in one partial test (or more) course credit could be awarded for the successful completing of the final test (ie, obtaining at least 60 points out of 100).
Condition for passing the exam is to obtain credit from the exercise of Analytical Chemistry II.
The exam is written test, evaluate the level of knowledge of theory and practice of analytical chemistry and creative approach to solving analytical problems.
Attendance at lectures is recommended, but not checked. Attendance at seminars is compulsory and is checked.
The students' work is controlled by three partial written tests during the semester in computational exercises.
For students in combined form of study are organized consultations on the topics for full-time students.
Consultations are also provided to full-time students on request.

Učební cíle

The aim of the course is to provide students with an overview of selected instrumental analytical methods from the field of electrochemistry, spectrophotometry and separation techniques and to familiarize them with their application fields and their limitations.
By completion of the course the student will gain the following knowledge and skills:
