High Performance Liquid Chromatography (HPLC) Method for Analysis of L-Carnitine and Arginine

L-carnitine is a quaternary ammonium cation (also known as a quat) that is key to the metabolic processes of most living species. Arginine is an alpha amino acid that is key to the biosynthesis of proteins.
These two amine-based compounds can be detected in the low UV regime. Using a Primesep 100 mixed-mode column and a gradient mobile phase consisting of water and acetonitrile (MeCN) with a gradient of sulfuric acid (H2SO4) as a buffer, L-carnitine and Arginine can be retained, separated, and analyzed. This analysis method can be UV detected at 205 nm.

 

 

Condition

Column Primesep 100, 4.6×150 mm, 5 µm, 100A
Mobile Phase MeCN/H2O – 20/80%
Buffer Gradient H2SO4 from 0.1 to 0.5%, 10 min
Flow Rate 1.0 ml/min
Detection UV, 205 nm
