A) A mass spectrum of a sample containing mixture of ions obtained with a 13-m serpentine path TW SLIM IMS module. B) IMS separation for a mixed sample obtained by TW SLIM at the optimum conditions: TW speed of 148 m/s, TW amplitude of 30 V, guard bias of 5 V, RF amplitude of 220 Vp-p at 650 kHz, and 2.75 mm gap at 3.00 Torr. C) Nested mass and IMS spectrum. (D) Extracted TW SLIM IMS separations for individually nanoelectrosprayed LNFPi (blue) and LNFPii (red) (m/z [M + Na]+ = 876) ions and (E) a mixture of LNFPi and LNFPii (m/z [M + Na]+ = 876). (F) A 90 cm DTIMS separations for LNFPi and LNFPii (m/z [M + Na]+ = 876) ions obtained at 19 V/cm is shown for comparison.40 Adapted with permission from ref. 40, Copyright (2016) American Chemical Society.
