Photodissociation of trapped ions selected by drift-time separation. IMS-UVPD-MS

摘要

We have trapped and photo-dissociated ions selected in function of their drift-time through an IMS cell. These first results show the feasibility and the vast potentiality of implementing photo-excitation to an ion mobility mass spectrometer. This system enables various approaches on many systems such as isobaric molecules, protein conformations and spectroscopic/FRET studies.
