Bimolecular ions of up to MDa size with thousands of charges have recently been trapped and studied in this laboratory using electrospray ionization (ESI) and Fourier transform ion cyclotron resonance mass spectrometer (FTICRMS). For structural analysis, multiply charged ions generated by ESI can be dissociated at the interface, by collision induced dissociation (CID) or Surface induced dissociation (SID). However, charge exchange with the surface and charge partition among the fragments significantly complicate the SID and CID spectra of multiply charged large ions. High resolution FTICR is an ideal solution to this problem.
