Mass spectra derived from transmission mode ion/ion proton transfer reaction: (a) 12-ms positive nano-ESI of 10 μM bovine ubiquitin (trapped), (b) post-ion/ion spectrum after 50-ms negative nano-ESI of 200 uM PFO passing through a population of ions shown in (a), and (c) ion parking (75.8 kHz, 3.7.0 V0-p) mass spectrum.
