HPLC Determination of Streptomycin on Primesep 200 Column

May 9, 2019

HPLC Determination of Streptomycin sulfate salt on Primesep 200 Column
Streptomycin is an antibiotic used in treating bacterial infections and has also been used as a pesticide. It is on the World Health Organization’s (WHO) list of essential medicines. It works by inhibiting the synthesis of proteins. It can be retained on a Primesep 200 mixed-mode column by hydrophobic and ion-exchange properties. The analytical method uses MS-compatible mobile phase of acetonitrile (ACN) and water with sulfuric acid (H2SO4) buffer. Also capable of UV detection at 200nm.

Condition
Column Primesep 200, 4.6×150 mm, 5 µm, 100A
Mobile Phase MeCN/H2O – 10/90%
Buffer H2SO4 – 0.05%
Flow Rate 1.0 ml/min
Detection UV, 200 nm

Separation of Streptothricins on Newcrom R1 HPLC column

Streptothricins can be analyzed by this reverse phase (RP) HPLC method with simple conditions. The mobile phase contains an acetonitrile (MeCN), water, and phosphoric acid. For Mass-Spec (MS) compatible applications the phosphoric acid needs to be replaced with formic acid. Smaller 3 µm particles columns available for fast UPLC applications. This liquid chromatography method is scalable and can be used for isolation impurities in preparative separation. It also suitable for pharmacokinetics.

Application Column

Newcrom R1

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.
