Popis: In-capillary derivatization using fluorescamine as the labeling reagent was proposed to enhance the detectability of adamantine drugs (memantine, amantadine and rimantadine) by spectrophotometric detection. Fluorescamine and the drugs were delivered to the capillary electrophoresis instrument at a ratio of 10:1 by zone injection. The derivatization reaction occurred following the application of voltage (20 kV). The derivatized products, hydrolyzed- fluorescamine and excess fluorescamine were separated in 7 min using 100 mM borate buffer (pH 10.0) containing 0.1% w/v of Brij®-35 and 20% v/v of acetonitrile. Validation data showed good linearity (r2 > 0.98), precision (%RSDs
