Learning outcomes Develop the students' ability to understand the theoretical knowledge underlying the analytical methods commonly used in chemistry and biology laboratories and interpret the corresponding results. At the end of this course the students should be able to: - Know the basic operation principles of some of the most commonly used equipment in chemical analysis laboratories and know how to use it properly.
- Evaluate the benefits and limitations of different instrumental methods.
- Select an appropriate instrumental method to solve a problem in a case study, based on the theoretical knowledge and using the scientific literature as a resource.
- Interpret, explain, and accurately express analytical results.
- Be familiar with analytical methods validation procedures.

Teaching Methodologies and Assessment Criteria Teaching in this curricular unit is structured into theoretical and laboratory classes. Lectures are taught with the help of audio-visual media and give an overview of the techniques studied, with emphasis on understanding the most important underlying concepts. Throughout the semester students have laboratory classes using instrumental methods. There are also practical lessons where knowledge is developed through problem solving.
The evaluation will tend to be continuous, and take into account two factors of evaluation: 30% Practical + 70% Theoretical.
Language Portuguese. Tutorial support is available in English.
