a first processing unit comprising a first controller, a dispensing section, a first measuring section and a first holder, wherein the first measuring section is configured to perform a first measurement on a sample contained in a first container in a first cycle, and the first controller is configured to control the dispensing section and the first measuring section;

a second processing unit comprising a second controller, a second measuring section and a second holder, wherein the second measuring section is configured to perform a second measurement on a sample contained in a second container in a second cycle different from the first cycle, and the second controller is configured to control the second measuring section;

a relay section which is disposed between the first processing unit and the second processing unit, wherein the relay section has at least one holding hole for holding the second container and includes a detector that detects the second container held by the at least one holding hole, and the first controller and the second controller are independently connected to the detector; and

a transport unit that is different from the relay section and that is configured to transport at least one sample container to a dispensing position of the dispensing section of the first processing unit;

wherein the dispensing section is configured to dispense a sample contained in the at least one sample container positioned at the dispensing position into the first container and the second container in the first processing unit,

wherein the first controller of the first processing unit is further configured to perform a transferring operation of transferring the second container to the relay section by the first holder, and the second controller of the second processing unit is further configured to perform a receiving operation of receiving the second container, from the relay section by the second holder, that has been transferred to the relay section by the first holder.
