Amino Acid Analyzer

Our Amino Acid Analyzer employs continuous flow ion exchange liquid chromatography to detect amino acids in protein hydrolysates. It has a flow rate range of 0.001 to 10 ml/min. Automated procedures and makeshift ion-exchange resins speed up analysis. Due to high sensitivity, amino acid measurement uses low-concentration samples. The equipment includes reagents, buffers, and columns for analysing amino acids in food hydrolysates and physiological fluids.
