AB  - A kinetic method for the determination of l-tyrosine (Tyr) by analyte pulse perturbation, caused by different amounts of Tyr, in the Bray–Liebhafsky (BL) oscillatory reaction realized in a continuous-flow stirred tank reactor, is proposed. For such purposes, the BL oscillating reaction was kept in a stable non-equilibrium stationary state close to the bifurcation point and was used as the matrix reaction system. Under optimum reaction conditions, the linear relationship between the kinetic parameters, Δτ2 (the period between first two oscillations that appear after applied perturbation) as well as τend (the time elapsed between the perturbation of the BL reaction by Tyr and the termination of the oscillatory phase) and the Tyr concentrations is obtained over the ranges 1.1 × 10− 6 − 9.2 × 10− 6 mol L− 1 and 1.1 × 10− 6 − 1.4 × 10− 5 mol L− 1, with the limit of detections of 6.6 × 10− 7 mol L− 1 and 6.4 × 10− 7 mol L− 1. The described method that relies on a simple instrumental set-up, has been successfully applied to the determination of Tyr in a dietary supplement. Some aspects of the possible mechanism of Tyr action on the BL oscillator are discussed.
