LECTURES
The theoretical foundations of each topic will be explained in the lectures, using the board and visual aids. Topics will be illustrated with examples of pedagogic value, problems related to the analytical techniques studied, and some of their applications to Chemistry Engineering. The explanations will be supplemented with basic teaching resources and new technologies: use of Learning Management System, videos, slide presentations,...
INTERACTIVE SESSIONS (SEMINARS)
The Lecturer will give the student sets of problems and case studies before the seminars. The lecturers will solve some of the problems in the board, and the students will be also encouraged to solve, present and discuss similar exercises. Some of the exercises done by the students will be collected for the assessment. The lecturer can also use slide presentations, visual aids… Seminars will be used for supervision, presentation and discussion of the academic works proposed during the term (maximum number of academic works: 2).
Attendance at these lessons is compulsory.
GROUP TUTORIALS
There will be meetings with the lecturer to discuss course work or to clear up points arising from the lectures and seminars, and to prepare lab sessions. Attendance at these lessons is compulsory (2 hours/student).
INTERACTIVE SESSIONS (LAB SESSIONS)
Laboratory work is essential in Analytical Chemistry and it will consist of a set of experiments to illustrate some of techniques and methodologies studied in this course. Students will analyse “unknown samples” using the different techniques and will also learn safety measures and how to use lab equipments.
Students will have available a lab manual with the basic principles, methodologies, calculations and proceedings for each experimental session. Students have to read carefully this manual before entering the lab, and make the calculations needed for each day. They will use Excel in the lab to treat the experimental data and obtain the desired results (usually a concentration value).
After a short explanation and a discussion with the lecturer, students will perform the experiments individually or in small groups. Each student will record his or her own data, make the calculations, answer the questions and write a report. At the end of the lab sessions, each student must submit his or her report to the lecturer who will evaluate this work.
The student must attend the lab sessions and write a report about his/her work to pass the course. The assistence to those lab sessions is mandatory.
The competences to adquire are:

7) Lab exam (CG3,CG4,CG8,CG10,CT2,CT3,CT4,CT5,CT6, CT7, CT12, CT13)
The evaluation will consist of:
- Final examination: 40% of the final mark
There will be a comprehensive final examination at the end of the term. This exam will be composed of theoretical and practical questions and exercises. If the student fails, she or he will have a second chance in July, and the student will also repeat the part of the exam corresponding to the lab. The grade obtained during the continuous assessment will be also used to calculate the final mark.
- Laboratory grading: 24 % of the final mark.
The attendance to the lab lessons (15 hours) and the submission of the lab report are compulsory to pass the course. The evaluation will be performed by observing the competences acquired in the lab and the quality of the experimental work, the laboratory report and an examination related to the topics treated (quality of the experimental work+ lab report: 14% of the final mark; exam: 10% of the final mark).
- continuous assessment: 36% of the final mark. Attendance to the lectures and participation in the seminars, discussions, and tutorials will be evaluated. Assignments (exercises, supervised works) will also be evaluated.
