Method and instrument for quantitative analysis
专利汇可以提供Method and instrument for quantitative analysis专利检索，专利查询，专利分析的服务。并且PURPOSE: To improve the accuracy of measurement by disposing an anode and reference electrode via a salt bridge at the time of making quantitative measurement of hydrogen peroxide by using electrodes.
CONSTITUTION: A quantitative analysis instrument 1 is provided with an element 10 for quantitative analysis and a voltage applying device 20 for impressing a prescribed voltage to the element 10. The voltage is applied to the instrument 20 in such a manner that the electrode 11 acts as the anode and the other electrode 13 as the cathode. A water absorptive member 12 is brought into tight contact with the two electrodes 11, 13. The voltage to be applied between the electrodes 11 and 13 is required to be constant and the specified voltage is applied between the electrodes 11 and 13 by using a potentiostat 26. On the other hand, the reference electrode 27 is connected via the salt bridge 14 and an electrolyte soln. 15 to the member 12. The electrode 27 is prevented from being affected by the enzyme reaction which arises in the member 12 by providing the salt bridge 14 and the soln. 15 between the electrode 27 and the member 12 in the above-mentioned manner. The measurement accuracy of the current value is, therefore, improved.
