HPLC analysis of glycosylated amino acids

Analysis of Plasma Amino Acids Using RP-HPLC and Pre-Column Derivatization with OPA/3-MPA

ABSTRACT        Background and Objective: Measurement of amino acids is an important tool for metabolic studies and evaluation of patients’ clinical condition. The aim of this study was to analyze the plasma amino acids using reverse phase high performance liquid chromatography techniques (RP-HPLC) with pre-column derivatization by o-phthalaldehyde (OPA)...

Performance of 2-Amino Tetraphenyl Porphyrin as Stationary Phase in RP-HPLC of Amino Acids

The search for new stationary phases has been one of the predominant concerns in high performance liquid chromatography (HPLC) in order to achieve better resolutions, longer column lives, and reduce the time of analysis. A chromatographic packing for separation of underivatized amino acids (AAs) were prepared by dynamically coating 2-amino tetraphenyl prophyrin (atpp) on a C-18 reversed-pha...
