Learning Objectives

The aim of the course is to provide a first framework for the overall synthesis of analytical chemistry, addressing principally the fundamentals and the use of some of the most important instrumental quantitative techniques of analysis and requiring a deep integration of the previously acquired knowledge in the field of analytical chemistry and placed at the end of the study path to exploit the student's maturation.

Course Structure

The course will be carried out through a first part of lectures to provide the student with the basic background for the design of experiments and the use of advanced analytical tools, and a part of the laboratory that provides participated lessons, simulation and the execution of rigorous quantitative analysis with single and group work typology. In the final part of the workshop the students will be invited, under the professor supervision, to create independent working groups which will choose a case study. Each team deal with the analytical problem through the following self-organized work scheme: bibliographic research, feasibility, sampling, choice of analytical method, instrumental analysis, interpretation of the final data and discussion / comparison of their results in the classroom in the presence of the other teams through a multimedia lecture.
