The major reasons for this include greater sensitivity, faster analyses, and the ability to use less expensive, more flexible HPLC instrumentation rather than dedicated amino acid analyzers.

Wolfgang Jagodzinski,Markus Kleinwhich are shown in .. Amino acid analysis has an important role in the study of the composition of proteins, foods, and feedstuffs. Free amino acids are also determined in biological material, such as plasma and urine, and in fruit juice and wine. When it is performed on a pure protein, amino acid a

Sample contaminants contribute to background noise that hampers amino acid analysis, variably affecting recoveries of individual amino acids (.). The necessity to obtain samples in high conc

Waldemar Koch Dr.-Ing. Dr. Phil.nique was utilized with glassy carbon electrodes and in the mode of constant potential amperometry. The first widely used applications were for catecholamines and their derivatives (.). Today, most laboratories around the world still rely on electrochemical detection when it comes to analyzing catec
