摘要：

Nonaqueous capillary electrophoresis (NACE) has been used to achieve rapid separations of basic drugs. A high electric field was obtained by using short capillaries, Baseline separations of basic drugs, including amphetamines, tropane alkaloids and local anesthetics, were achieved in I min by selection of the appropriate organic solvent and electrolyte composition. Thus, high-throughput analyses can be performed. Peak efficiency up to 9154 theoretical plates s(-1) was achieved in a separation performed at 923Vcm(-1). No discernible loss in resolution was observed when a conventional capillary (64.5cm) was replaced by a short (32.5cm) capillary.
