SLIM SUPER IM separations of Aβ peptide epimer sets as (A) [M + 2H]2+ adducts, (B) [M + H + Na]2+ adducts, and (C) [M + 2Na]2+ adducts. Peptide epimer sets 1–4 and 13–16 were subjected to a 72 m SLIM SUPER IM separation, while 99 m of separation was needed for 9–12. For individual IM peak assignments, see the Supporting Information.
