High Performance Liquid Chromatography Incorporating to Short Column and Micellar Mobile Phase for Determination of Some Contraceptive Drugs
In this research, reverse-phase high performance liquid chromatography using green mobile phase utilizing short column was developed for the determination of some contraceptive drugs such as ethinyl estradiol (EE), cyproterone acetate (CPA), gestodene (GES) and levonorgestrel (LNG). This Zorbax SB-C...
