Our Amino Acid Analyzer, uses continuous flow ion exchange liquid chromatography to provide both qualitative and quantitative information on the amino acid composition of a protein hydrolysate and has a flow rate range of 0.001 to 10 ml/min, is an automated and reliable tool for identifying amino acids in protein hydrolysates. By employing automated techniques and improvised ion-exchange resins, we decreased the analytical time. Amino acid quantification employs samples with low concentrations due to its excellent detection sensitivity. For the analysis of amino acids in food hydrolysates and physiological fluids, the apparatus is developed with a full operational system that comprises a range of easily accessible reagents, buffers, and columns. With the assistance of a UV/VIS detector, one can ensure that the work is conducted exactly, accurately, and in compliance with standards. There are numerous applications for it in biochemical research, nutrition research for both humans and animals, medical diagnostics, and pharmaceutical, food, and feed control.
