Objectives
The course aims at providing a broad and in-depth knowledge of modern mass spectrometric analysis methodologies. Coupling of separation techniques, as well as qualitative and quantitative data analysis included. The different mass spectrometric techniques are compared in detail and evaluated for different applications and analytical problems.
Learning outcomes and competences
Mass spectrometry is accomplished in modern instruments with some complexity. Its effective use requires a sound knowledge of the principles of operation, which involves the understanding of phenomena and techniques associated with the ionization, fragmentation and spectral scanning. To this end, the syllabus embodies all the support concepts and basic phenomena for understanding the current techniques of ionization, mass detection, analysis and data processing.
On a practical level, given the paramount importance that the use of mass spectrometry associated with the chromatographic separation assumes, the practice of actual use of instrumentation to data acquisition will be held with chromatographic coupling, one of the topics of the programme. The last topic, MS/MS, assumes a great importance, in particular in situations of complex analysis. The ability to suggest the appropriate mass spectrometry methods for unusual or special applications, will thus derive essentially from these last topics.
Learning outcomes - After completing the course the student will:
- acquire the principles of common mass spectrometric instruments.
- be able to account for common ionization and separation techniques, as weel as fragmentation modes;
- acquire practical skills from real instrumentation, as well as to evaluate, quantitative and spectral data;
- be able to suggest suitable mass spectrometric methods for ordinary or particular applications.

Teaching methods and learning activities
The course provides theoretical and practical skills. Whilst dialectic between these two aspects is intended, the eminently theoretical part is played in the classroom, in a theoretical-practical approach involving discussion, problem-solving and information research.
The practical aspect will be essentially developed in the laboratory, allowing, in a first phase, a familiarization with interpretation of mass spectra and different instrumentation of mass spectrometers. In a second phase, laboratory work is carried out, allowing the application of concepts seized to data acquisition and its interpretation, with the purpose of instrumental performance test or quantification.

Eligibility for exams
Students who miss more than 25% of the expected number of theoretical-practical (TP) and practical laboratory classes (PL) will lose their attendance at this UC.Calculation formula of final grade
The assessment will be distributed, taking into account the components of practical work with report (25%) , presentation/discussion of scientific article (15%) and final written examination (60%). Approval is conditioned to a minimum mark of 9.5 (out of 20) in the final written examination.
Special assessment (TE, DA, ...)
The special assessment will be distributed, taking into account the components of practical work with report (25%) , presentation/discussion of scientific article (15%) and final written examination (60%). Approval is conditioned to a minimum mark of 9.5 (out of 20) in the written examination.
Classification improvement
The student may require to improve the component of final written examination.
