This is a dedicated amino acid analyzer for high end analysis of amino acids in research, in clinical laboratory (i.e. newborn screening), in quality control for Food (own patent 10 2016 010 887), Beverages and Feedstuff. It works according to gold standard of post column derivatization with ninhydrin, with detection at 440 nm and 570 nm using maintenance free LED photometers. A separation of up to 44 amino acids in about one hour is possible (55% faster than traditional), but also of a few amino acids within a few minutes. The setup of the instrument allows the continuous analysis of 96 samples in a cooled autosampler. The pump allows the simultaneous operation of two fluid lines (eluent side and reactive side), which guarantees a constant mixing.
