(a) Example of positive-mode targeted 213 nm UVPD spectrum from a mouse cerebellum sample for the precursor ion of m/z 748.53 with (b) fragment map showing identification of the lipid as PE(P-16:0/22:6(Δ4, Δ7, Δ10, Δ13, Δ16, Δ19)). The mass accuracy values of the assigned fragment ions are shown in Table S10.
