Mass spectra of an equimolar six-component protein mixture (a) prior to and (b) after a parallel parking (vide infra) ion/ion reaction period and (c) after an ion/ion reaction period sufficient to reduce charges largely to +1.Perfluoro-1-octanol (PFO) anions were used as proton transfer reagents and ~100–200 ms reaction times were used in b and c.
