(a) Schematic representation of the TENG TAP fragmentation IM-MS instrumentation used in the present work. (b) Schematic of the large-area TENG ion source. Displacement of the TENG sliding electrode generates a transient corona discharge accompanied by electrospray, promoting unsaturated lipid epoxidation. (c) Schematic of the most relevant events in TAP fragmentation IM-MS experiments, enabling mobility-resolved MS3 analysis. (d) Ion packages separated by ion mobility and fragmented in the trap collision cell are monitored by time-of-flight (ToF) MS.
