Abstract :
A method for the quantification of five congener ephedrines in urine samples without sample preparation was developed. The analytes were trapped on a C18 precolumn and separated on a C18 BDS analytical column. Baseline separation was achieved for all analytes. The method meets the requirements of the International Olympic Committee (IOC) medical commission regarding cut-off limits for positive doping cases with ephedrines.
