✦ Synopsis
Proton spinÈlattice relaxation rate constants values) of some selected urinary metabolites were (T 1 analysed extensively by two di †erent least-squares minimization procedures, based on the simplex and the MarquardtÈLevenberg algorithms. Comparative multiplicate analysis under di †erent experimental conditions using laboratory solutions of some of the urinary metabolites was employed in addition to direct measurements on human urine samples. The values estimated for most of the metabolites by the two methods agreed to within T 1 10È15%.
