A novel method based on microemulsion electrokinetic chromatography (MEEKC) for rapid determination of caffeine in commercial and clandestine stimulants, known as ‘‘energy drinks’’ and ‘‘smart drugs’’, is described. Separations were carried out in 50 cm x 50 um (ID) uncoated fused silica capillaries using voltage of ěé kV and buffer electrolyte was composed of 8.85 mM sodium tetraborate pH 9.5, SDS 3.3% (w/v), n-hexane 1.5% (v/v) and 1-butanol 6.6% (v/v)
