The course is aimed at introducing the students to the modern analytical chemistry, providing basic theoretical and operational information on sample preparation and instrumental analysis by spectroscopy, electrochemistry, chromatography and mass spectrometry techniques.
Knowledge of the main sample preparation techniques, choice of the appropriate procedures in regard to the subsequent instrumental analytical techniques. Basic theoretical knowledge of the main chromatografic, mass spectrometric and electrophoretic techniques. Development of the ability to choose and carry out an analytical method, to perform experiments in groups and to report the results.

CHIMICA ANALITICA 2 (1° MODULO)

All class schedules are posted on the EasyAcademy portal.
Questionnaires and reports on laboratory work, performed during the course.
Written test and oral examination.
Evaluation is based on questionnaires and individual reports relating to laboratory experiments, written test and oral examination. In particular, the laboratory score is calculated from the sum of the votes of individual experiences, obtained as follows: (a) participation to a preparatory quiz before each experience: 2 points for each quiz passed. Each quiz consists of 10 multiple-choice questions and it is passed when all answers are correct. Attempts are unlimited; (b) preparation of a short report for each experience containing data processing and the analytical results: rating from -1 to +1 for each report (-1: not correct; 0: partially correct; + 1: correct), taking into account the correctness of data processing, presentation and the accuracy of the results. The written test lasts 1.5 hours and it is composed by four exercises, aimed at assessing the individual skills to process analytical data, calculate the figures of merit of an analytical procedure, and propose a method for a given analytical problem. A score is assigned to each exercise according to its difficulty. A minimum score of 18/30 is required to access the oral test. The oral examination, performed by two professors and about 40-min long, is aimed to assess the knowledge of the theoretical content of the course. During the examination, the commission evaluates if the educational objectives of the course have been achieved. If not, the student is asked to study more thoroughly and/or take benefit from further explanations by teachers. The final grade is obtained from the weighted average of the laboratory vote, and the written examination and oral assessments. The relative weight of the three assessments takes into account the number of credits of each part of the course on which assessments are based (25% laboratory; 25% written exam 50% oral). Rules on the written test: (a) the score is valid for three consecutive exam sessions; (b) in the case of double failure of the oral exam, the written test must be repeated; (c) the delivering of a new written test automatically cancels the previous score.
