Aims
At the end of this learning unit, the student is able to : | |
| 1 | This course covers technical aspects of mass spectrometry and interpretation of spectral data. |
Content
After a brief survey of the basic definitions, the various mode of ionization (EI, CI, FAB, ESI, APCI, APPI, DESI, DAPCI, DAPPI) will be described in details. The different analyzers (Quad, triple Quad, Traps, TOF, Orbitrap, FTICR) will be presented together with their possible scanning modes and their combinations. Couplings with Gc and HPLC will be presented. The interpretation of spectral data will first emphasize the differences between low resolution and low accuracy versus high resolution and high accuracy data. The importance of the isotopic cluster will be demonstrated. The principal rules of fragmentation of radical-cations will be presented together with some basic rules for the fragmentation of ions with even-number of electrons. Selected examples and exercises will be explicitly studied in this part of the course. At the end of the course, several examples of the utility of mass spectrometry for different domains will be seen through the presentations of the students.
Evaluation methods
Due to the COVID-19 crisis, the information in this section is particularly likely to change.
The participation to all the activities of the course is mandatory to validate the course and be allowed to present the exam. The exam consist in a personnel work based on the scientific literature to be presented to all the other students following the course.
