CONCLUSIONS Dystonic reactions are rare events among pediatric patients treated for acute headache, but are more common with prochlorperazine than metoclopramide. In general counter-current chromatography systems, there are several off-column fittings between injector and column inlet, such as bends, valves, connecting tubes and joints. Due to these off-column fittings, the sample will diffuse in the mobile phase and form an irregular distribution when it flows from the injector to the column inlet. Thus, the concentration di
