Simultaneous quantitative UV spectrophotometric determination of multicomponents of amino acids using linear neural network

Simultaneous determination of multicomponents of six amino acids with a nov el chemometric technique-a linear neural network (LNN) algorithm is reporte d in this study. Based on the data correlation coefficient and standard dev iation method, 17 representative wavelength points are selected from the or iginal UV spectral data (343 points) as the original input patterns for LNN to build a neural network model. The results obtained only by iterating 15 times is satisfying, with a correlation coefficient of 0.999 and a relativ e small standard deviation. (C) 2001 Elsevier Science Ltd. All rights reser ved.
