Chromatograms of antiepileptic drugs (A–C) and anti-arrhythmic drugs (D–F) using crosslinked PNIPAAm modified-bead packed columns. (A) Lamotrigine, (B) Carbamazepine, (C) Phenytoin, (D) Quinidine, (E) Propafenone, and (F) Disopyramide. The mobile phase was 10 mM CH3COONH4 (pH 6.75) buffer solution with a flow rate of 1.0 mL/min.
