Rules for evaluation and completion of the course

Course credit is awarded for 100% attendance at seminars (or properly excused absence).
Credit may be obtained for successful completing of 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).

Examination consists of a written and oral part.

Attendance at lectures is recommended, but not controlled.
Attendance at seminars is compulsory and is checked.
The students' work is controlled by the partial written tests during the semester in computational exercises.
Consultations are provided on request.

Aims

The aim of the course is to give students overview about analytical chemistry, classical analysis, selected instrumental analytical methods from the field of electrochemistry, spectrophotometry and separation techniques and chemometric approaches for processing the results.
Increased knowledge, skills and competencies of students will be reflected mainly in the following areas:

1.Students will became acquainted with the theoretical foundations of analytical chemistry.
2. Students will have cognizance of classical qualitative and quantitative analysis methods.
3. They will know the principles of simple instrumental analytical methods and possibilities of their application.
4. They will adopt the basic principles of chemometrictreatment of analytical results obtained using simple instrumental-analytical methods.
5. Students will improve their skills in computing solutions to solve simple analytical problems.
