Ultrasensitive chemiluminescence (CL) detection of aM vanadium(IV) in capillary electrophoresis (CE) is first reported. In this work, inclusion of the luminol in the electrophoretic carrier electrolyte avoids the loss of light signal that occurs when luminol and hydrogen peroxide are mixed in advance, as in the conventional method in CE-CL detection.
