Bruker AmaZon quadrupole ion trap modified for laser photodissociation and spectroscopy

Electrospray ionization, 3D ion trap modified and coupled to a tunable OPO laser (195 to 2000 nm) pumped by a spectra-physics Quanta-ray pro 230-30 (355 nm). The instrument is used to study nucleic acid folding in solution and in the gas phase in soft conditions, and for the fragmentation of small molecules and non-covalent complexes.
