Abstract
A quantitative analyzing method is provided for electrochemically measuring the concentration of a substance in a sample liquid using a sensor including a reagent layer () which contains a reagent for reacting with the substance and to which () the sample liquid is introduced, and a first electrode () and a second electrode () for applying a voltage to the reagent layer (). The method includes a current measuring step for applying a voltage across the first electrode () and the second electrode () for measuring current flowing between the first and the second electrodes (), a parameter calculating step for calculating a parameter based on the measured current, and a determining step for determining a state of the sample liquid introduced to the reagent layer () based on the parameter and at least one predetermined constant.
