MULTICOMPONENT KINETIC-ANALYSIS IN LIQUIDS WITH A SINGLE LIPID-COATEDPIEZOELECTRIC CRYSTAL SENSOR USING ARTIFICIAL NEURAL NETWORKS

A single piezoelectric crystal sensor was used to simultaneously detec t two or three components in a liquid by obsening the kinetic adsorpti on process onto a synthetic multi-bilayer lipid membrane which was coa ted on both sides of the piezoelectric crystal sensor. The feed-forwar d artificial neural network (ANN) with back propagation (BP) training algorithm was used to do the data analysis. The correct rate of predic tion for the first sample set, 1-decanol and beta-naphthol, is 4.3%, f or the second one, 1-lauryl amine and alpha-naphthylamine, it is 4.8% and for the third one, sodium lauryl sulfate, sodium dodecyl benzene s ulfonate and N-cetyl pyridinium chloride, it is 5.2%.
