Abstract A radio frequency-free electromagnetostatic (EMS) cell devised for electron-capture dissociation
(ECD) of ions has been retrofitted into the collision-induced dissociation (CID) section of a triple
quadrupole mass spectrometer to enable recording of ECD product-ion mass spectra and
simultaneous recording of ECD-CID product-ion mass spectra. This modified instrument can be used
to produce easily interpretable ECD and ECD-CID product-ion mass spectra of tyrosine-phosphorylated
peptides that cover over 50% of their respective amino-acid sequences and readily
identify their respective sites of phosphorylation. ECD fragmentation of doubly protonated, tyrosine-phosphorylated
peptides, which was difficult to observe with FT-ICR instruments, occurs efficiently in
the EMS cell.
