Instrumental Techniques of Analysis

Recommended Prerequisites

General Chemistry and Organic Chemistry.

Teaching Methods

The course consists of lectures and laboratory practices.

Lectures supported by audiovisual presentations, including a problem solving component. Weekly laboratory practical classes, with the students organized in groups, and demonstrations/hands-on sessions involving the analytical methods studied. 

Learning Outcomes

The curricular unit aims to provide students with an adequate knowledge of the various instrumental methods of chemical analysis, particularly spectroscopic and chromatographic, as well as of several techniques for the environmental samples analysis and instrumentation for process assessment. The student should learn the theoretical principles underlying each technique, its applications, its limitations and the function of the main components of the instruments studied.

Ability to analyze, understand and apply acquired knowledge in the environmental engineering area at the professional approach level.

Acquire skills to communicate information clearly, with appropriate speech and means. Acquire skills in structured presentation of scientific materials and argumentation skills, both written and oral.

Acquisition of lifelong self-learning skills.

Work Placement(s)
