FIG. 1 shows a chemical analysis device that measures the amount of enzyme activity using a colorimetric method. In Fig. 1, 1 is a constant temperature flow cell installed in a constant temperature bath 10, and a pipe 2A.
It is configured to communicate with the sample container 2 through the pipe 4Af and with the sample suction and discharge pump 3 through the pipe 4Af. Reference numeral 4 denotes a valve for switching the flow path of the sample, and when the flow path is switched to the 4A side, the sample is sucked in, and when the flow path is switched to the pipe 4B side, the measured sample is discharged.
