Analytical Chemistry Ii with Lab

Goals
Acquisition of base knowledge about theory and application of the most common instrumental techniques, mainly spectroscopic ones, for elemental and molecular analysis

acquired skills
Ability to select the most adequate methodologies for solving a given analytical problem and interpreting their results at a base level

Course content
Choice criteria of an analytical method. Introduction to spectroscopic techniques. Methods for elemental analysis: optical atomic spectroscopy, atomic mass spectrometry, X-ray fluorescence. Methods for molecular analysis: IR and Raman vibrational spectroscopies, UV-visible absorption and luminescence spectroscopy, nuclear magnetic resonance, molecular mass spectrometry also combined with chromatographic techniques.

Suggested prerequisites
Chimica analitica I

Reference material
- D. A. Skoog, F. J. Holler, S. R. Crouch, Chimica Analitica Strumentale, EdiSES

Assessment method
Written: the exam is divided into two written tests, one for each module. For the Analytical Chemistry II module there is a questionnaire with 10 open-ended but short questions concerning the theoretical and applicative aspects of the analytical techniques covered in the course. The exam lasts 75 minutes.
For the Analytical Chemistry Laboratory module there is a questionnaire of 6 open questions concerning, also in this case, the theoretical and applicative aspects of the analytical techniques covered in the course; the exam duration is one hour.
For the final result, evaluations of laboratory practice reports will also be considered.
