HPLC Method for Analysis of Water-Soluble Vitamins (B1, B2, B3, B6) on Primesep 100 Column
August 28, 2024
High Performance Liquid Chromatography (HPLC) Method for Analysis of Water-Soluble Vitamins (B1, B2, B3, B6) on Primesep 100 by SIELC Technologies
Separation type: Liquid Chromatography Mixed-mode SIELC Technologies
High Performance Liquid Chromatography (HPLC) Method for Analysis of Vitamin B1 (Thiamine), Vitamin B2 (Riboflavin), Nicotinamide, Vitamin B6 (Pyridoxine), Pyridoxamine, Pyridoxal Phosphate
Water-Soluble Vitamins (B1, B2, B3, B6) can be retained, separated and analyzed using a Primesep 100 mixed-mode stationary phase column. The analysis employs an gradient method with a simple mobile phase comprising water, acetonitrile (MeCN), and sulfuric acid as a buffer. This method allows for detection using UV 300 nm.
You can find detailed UV spectra of Vitamin B1 (Thiamine), Vitamin B2 (Riboflavin), Nicotinamide, Vitamin B6 (Pyridoxine), Pyridoxamine, Pyridoxal Phosphate and information about its various lambda maxima by visiting the following links: Vitamins (B1, B2, B3, B6)

Separation of Pyridoxamine on Newcrom R1 HPLC column
February 16, 2018
Pyridoxamine 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.
