Capillary zone electrophoresis for the rapid screening of banned drugs in sport.

Capillary zone electrophoresis was used to analyze some drugs illegally used in sports. The spectroscopic characteristics and electrophoresis migration parameters of diuretics, narcotics-analgesics and beta-blockers were established. Analytical figures of merit including parameters on the precision of migration and limits of detection are discussed. Results for the separation of drugs of different doping families are discussed. An analysis of urine from a patient receiving daily doses of atenolol is presented.
