Conformational distribution of the 7+ charge state of ubiquitin showing, partially folded, and elongated structures as a function of voltage applied across the entrance funnel and the funnel RF amplitude. Plots A and E were generated on a TIMS-TOF MS and reproduced with permission by the Royal Society of Chemistry from [40], plots B – D were generated with Gated TIMS-FT-ICR MS.
