Applications:


HPLC Separation of Antibiotics
HPLC.cloud View on hplc.cloud Antibiotics are widely used for treatment and prevention of bacterial infections.  Various antibiotics, particularly those with a sulfanilamide structure, were separated in HPLC using mixed-mode columns with varying strengths of ion-pairing groups.  Primesep 200 has weak acidic ion-exchange pairing groups while Newcrom A has strong acidic ion-exchange groups.  In addition, methanol can be used in the mobile phase on Newcrom A column.  The antibiotics were resolved on both columns with a gradient mobile phase consisting of acetonitrile (ACN) or methanol (MeOH), water and sulfuric acid (H2SO4) buffer.  UV detection at 275nm.
