(a) Comparison between responses (peak area) of fragments obtained using CID (40 eV) and HCD (20 eV). (b) Comparison between CID fragmentation (40 eV) using the polarity switching function (ESI+ and ESI-) in the same injection and in two separate injections. Acquisition conditions: R= 25,000 FWHM and external mass calibration.
