A series of operations of taking out analytical implements, dipping them in the sample solution, optical measurement, calculation, and disposal of the used sample solution are performed automatically.The dip stage, in particular, is automated by use of an analytical-implement automatic supply device and an analytical implement automatic handling device which, holding an analytical implement, dips it in the sample solution, and sets it ona reaction turntable. A number of analytical implements are put in a storage section comprising a bottom section provided with an analytical implement groove and at least one inside surface which is parallel with the groove, are taken out one by one by the relative movement of the groove and in normal and reverse direction and by stopping in a specified position after confirming by a detector that an implement has been caught in the groove.

This measurement is carried out by scanning the measuring cell with a minute light flux periodically to obtain a plurality of measurements in a period. Out of the series of signals obtained, those containing abnormal scattered light signal are eliminated to determine accurate concentration and reaction process.

Abstract: A method for accurately performing concentration measurements while compensating the dilution ratio as needed during continuous measurement of specified ingredient in the liquid to be tested. The liquid to be tested is diluted by a diluent, wherein the liquid to be tested and the diluent or the mixture of the two and the diluent is transferred by means of the respective tube pumps to a measuring section. Either or both of the quantities of liquid-feeding of those two liquids are changed at the beginning of measuring or in an optional stage during the time of the measurement, diluted and mixed at two or more dilution ratios. Then the real dilution ratio at the time of changing the quantities of the said liquids is found on the basis of the measured value of the substance to be measured at the respective dilution ratios, and the concentration of the substance contained in the liquid to be tested is determined by using the real dilution ratio.
