Course/Module description:
The course gives basic knowledge in analytical chemistry, and covers wet and instrumental analytical chemistry techniques.
The aim of the course is to present to the students the needed knowledge for conducting quantitative analyses. Students will get acquainted with electrochemical, spectroscopic and chromatographic techniques.
Course/Module aims:
See Learning Outcomes.
Learning outcomes - On successful completion of this module, students should be able to:
Use analytical equipment for quantitative determinations.
Quantitatively analyze the measuring results by an analytical equipment.
Independently and intelligently evaluate the best analysis method.
Develop new analytical techniques.

Required Reading:
Slides of course presentation, and the relevant chapters in
Fundamentals of Analytical Chemistry, Skoog DA et al., 9th Ed.
Additional Reading Material:
Will be assigned in the lectures.
Course/Module evaluation:
End of year written/oral examination 100 %
Presentation 0 %
Participation in Tutorials 0 %
Project work 0 %
Assignments 0 %
Reports 0 %
Research project 0 %
Quizzes 0 %
Other 0 %
Additional information:
80% homework assignment submission is obligatory.
The final grade is composed of weighted averaging with the homework assignments submitted during the semester.
In case that a frontal lecture would not be possible the exam will be carried out as a home assignment
Some homework assignments will have heavier weight.
Under-submission of homework assignments will deduct upto 20 points from the final grade.
Missing more than 20% of the lectures (starting at the date of the initiation of the in-campus lectures) will deduct upto 10 points from the final grade.
We shall consider a mid semester exam which will provide 15% protective score.
