HPLC Determination of Streptomycin on Primesep 200 Column
May 9, 2019
HPLC Method for Streptothricins, Streptomycin B, Streptomycin on Primesep 200 by SIELC Technologies
High Performance Liquid Chromatography (HPLC) Method for Analysis of Streptothricins, Streptomycin B, Streptomycin.
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.

Separation of Streptomycin B on Newcrom R1 HPLC column
May 16, 2018
Streptomycin B 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.
