METHOD FOR MEASURING SUBSTANCES

摘要

Provided is a technique that enables measurement precision to be improved when quantifying a substance to be measured which is contained in a sample by decreasing the impact of current components different from the oxidation current resulting from the oxidization of a reducing substance produced by a reaction between enzymes and the substance to be measured in the sample among the current components in a response current obtained by applying a counter electode based measurement potential to a working electrode. Because an adjustment potential with higher potential than a measurement potential is applied in the form of a pulse to the working electrode among the current components contained in the response current obtained by applying the counter electrode based measurement potential to the working electrode the impact of the current components different from the oxidation current resulting from oxidization of the reducing substance produced by the reaction between the substance to be measured and enzymes in the sample can be reduced. Thus the response current can be stably measured and measurement precision can be improved when quantifying the substance to be measured which is contained in the sample.
