SLIM SUPER IM-MS separation of 1 μM sugar isomers lacto-N-hexaose and lacto-N-neohexaose were obtained at (A) 1 pass and (B) 9 passes under the optimum conditions: TW speed of 206 m/s, TW amplitude of 30 V, guard bias of 15 V, RF amplitude of 340 Vpp at 822 kHz, and 2.75 mm gap at 2.50 Torr. The structures are illustrated in left panel.
