Separation of Steroids in Reverse and Normal Mode on Primesep 100 Column

The separation of steroids on Primesep 100 demonstrates the versatility of Primesep columns in both reversed- and normal-phase modes. Switching modes by changing the mobile phase reverses peaks 2 and 3. The separation method uses a mobile phase mixture of water and acetonitrile (MeCN, ACN) for reversed phase and hexane and ethanol for normal phase with UV detection at 240 nm.
