PURPOSE:To shorten the time required in titration to a large extent and to perform accurate titration, by a method wherein a titration liquid is injected until exceeding a final point and an over-titration part is compensated to calculate the injection amount of the titration liquid. CONSTITUTION:When the amount of an injected titration liquid when an indication amount exceeds a final point value while a titration liquid is stepwise injected is set vn, the change amount of the indication value to e1 and the difference of the indication value and the final point value to e2, an over-titration amount is calculated by a formula x e2Xvn/e1 and, when the amount of the titration liquid of each time is set to v1, v2..., the total injection amount is calculated by a formula V SIGMAvi-x. When titration about one sample is performed, separate samples are subsequently successively added to perform continuous titration. In this case, because the titration liquid is injected in an excessive amount corresponding to the over-titration amount (x) from the begining, an error can be corrected by performing correction by adding the previously calculated over-titration amount (x) to the total injection amount V. It is unnecessary to make the injection amount of the titration liquid minute in order to coincide the indication value and the final point value. |
