摘要:
A surface-normal surface-induced dissociation (SID) configuration specifically designed for coupling ion mobility spectrometry (IMS) and orthogonal time-of-flight (TOF) mass spectrometer is described. The instrument configuration and the effects of various operating parameters are critically evaluated using ion trajectory calculations (SIMION) and SID spectra of a series of model peptides. The utility of the instrument configuration for simultaneous acquisition of MS and MS-MS spectra in both data-dependent and non-data-dependent modes are also discussed. (c) 2006 Elsevier B.V.
