A new flow-injection ESR system (FI-ESR) special for the quantitative spin-trapping ESR measurements is developed to estimate the second-order rate constants (<I>k</I><SUB>s</SUB>) of the reaction between hydroxyl radical and selected scavengers, glycine, mannitol, and 4-hydroxycoumaric acid. The <I>k</I><SUB>s</SUB> values of these scavengers show reasonable agreement with those evaluated by pulse radiolysis method.
