Abstract
Abstract (D This is on an autonomous continuous analysis method and apparatus using Dip and Read type analytical implements. 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 on a 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, and are taken out one by one by the relative movement of the groove 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.
