Amino Acid Analysis System

Description

This amino acid analysis system from Shimadzu is a dedicated HPLC configuration for the sensitive and selective quantification of amino acids. Its core detection method is post-column fluorescence derivatization, utilizing reagents such as o-phthalaldehyde (OPA) and N-acetylcysteine. This approach offers significant advantages, including high sensitivity—reportedly over ten times greater than traditional ninhydrin methods with UV detection—and excellent selectivity for compounds with primary amino groups. The post-column reaction design enhances reproducibility, as the derivatization occurs after chromatographic separation, minimizing interference from the sample matrix. System operation is streamlined with features like automated reagent mixing and available mobile phase and reagent kits to simplify solution preparation. It is applicable in fields such as food science, pharmaceuticals, and natural product research.
