It is a raw bird. Therefore, in the case of manual analysis, the above-mentioned mixture of the two
Errors caused by dispensing operations were likely to occur. Furthermore, in an automatic analyzer, it is essential to automatically perform mixing, dispensing, reacting, and transferring a sample, reagent, etc. to a detection section. For example, in order to mix a sample and one type of reagent in predetermined amounts and send the mixture to the detector, two ponders are used to send predetermined amounts of each sample and reagent to a mixing tank.
After warming them in a mixing tank, it is common to use another ponder to send the mixed sample and reagent to the detection section69. In this case, there are three ponders, a mixing tank, and a mixing tank. A control unit etc. for controlling the above is required, making the configuration complicated.
