OVERVIEW

The course is aimed at introducing the students to the modern analytical chemistry, providing basic theoretical and operational information on instrumental analysis by spectroscopy, electrochemistry, chromatography and mass spectrometry techniques.

AIMS AND CONTENT

LEARNING OUTCOMES

Basic theoretical knowledge of the main spectroscopic and electrochemical techniques. Practical knowledge of the preparation of samples and their analysis using these instrumental techniques. Development of the ability to conduct an analytical method, carry out experiments in groups and write reports on the results obtained.

AIMS AND LEARNING OUTCOMES

Participation in the proposed activities (lectures, classroom and laboratory exercises) and individual study will allow the student to:
1) understand the basic concepts of instrumental analytical chemistry and the theoretical and operational aspects of the main spectroscopic and electroanalytical techniques.
2) process analytical data (from the measurement of the analytical signal to the final results) and to calculate the main figures of merit of the analytical methods.
3) conduct simple analytical procedures of sample preparation and analysis using spectroscopic and electroanalytical techniques.
4) communicate the results of an instrumental analysis through a written report.

TEACHING METHODS

The unit is divided into lectures in which the theoretical concepts relating to the instrumental analytical techniques are presented and various application examples are analysed (40 hours), participatory teaching activities (6 hours), and laboratory exercises carried out in groups (20 hours). In their personal work, the students will have to acquire the theoretical knowledge of the instrumental techniques, process the data obtained during the laboratory exercises by using a specific form, and practice processing analytical data and calculating the analytical figures of merit. Personal study is supported by specific teaching material on AulaWeb.
