HPLC Separation of Antibiotics
June 11, 2020
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.

Application Column
Primesep 200
The Primesep family of mixed-mode columns offers a wide variety of stationary phases, boasting unprecedented selectivity in the separation of a broad array of chemical compounds across multiple applications. Corresponding Primesep guard columns, available with all stationary phases, do not require holders. SIELC provides a method development service available to all customers. Inquire about our specially-tailored custom LC-phases for specific separations.
Select optionsNewcrom A
The Newcrom columns are a family of reverse-phase-based columns. Newcrom A, AH, B, and BH are all mixed-mode columns with either positive or negative ion-pairing groups attached to either short (25 Å) or long (100 Å) ligand chains. Newcrom R1 is a special reverse-phase column with low silanol activity.
