Mass Spectrometry and Gas Phase Ion IR Spectroscopy (CHIM/03)

Attività di ricerca

From the single molecule to the supramolecular architecture

Study of molecular recognition mechanisms by investigating the nature and strength of the noncovalent interactions stabilizing both naked biomolecules conformations and supramolecular architectures. Chirality of systems under investigation is a further structural probe exploited to describe the three-dimensional arrangement of a guest into a supramolecular device. To this aim, Electrospray-InfraRed MultiPhoton Dissociation-Mass Spectrometry (ESI-IRMPD-MS), which combines the wide applicability of the ESI source, the m/z selectivity of the MS (Paul-type Ion Trap) and the structural resolving power of a tunable IR laser beam (OPO/A device) is applied. The unique diagnostic power of this layout allowed us to deal with both the assignment of the protonation site and the conformational freedom of multifunctional species as well as with the stereochemical investigation of noncovalent supramolecular complexes, including chiral species. The dissociation of the mass selected species is also collisionally activated, to gain preliminary structural and thermodynamic information.

Untargeted analysis of vegetable and food matrices

A further experimental field our research is actively contributing is the analytical investigation of vegetable (several cannabis sativa L. cultivars, satureja montana L.) and food (sedano, garlic) matrices performed through Gas Chromatography-Mass Spectrometry (GC-MS), coupled with a sample pre-concentration by means of HS-SPME (head space-solid phase microextraction), where required.
