In this work, tetraalkylammonium amino acid ionic liquids (TAA-AAILs) were first applied to non-aqueous capillary electrophoresis (NACE) to establish synergistic systems with a conventional chiral selector, native β-cyclodextrin (β-CD). Excellent enantioseparations of some dansyl-amino acid (Dns-AA) samples were achieved. A
