The separation of seven analogous anabolic steroids was studied by micellar
electrokinetic capillary chromatography (MECC). The retention order was fo
und to be dependent on polarity. All of these steroids were well separated
by the addition of organic modifiers to the separation buffer. Of the organ
ic modifiers tested, 1-propanol gave the best separation, better than metha
nol or acetonitrile.
