ANALYZING SYSTEM

摘要

In an analyzing system including a commanding unit for sending a command and an executing unit for executing a processing upon receiving the command, a processing instruction may not be executed at the right time due to a heavy traffic of information and other factors. In order to solve this problem, in a preparative separation system 1 according to the present invention, a PC 20 provides the execution time for starting/finishing the fractionation processing to a controller 18. Therefore, even in the case where the time of the PC 20 and that of the controller 18 are not synchronized, the controller 18 can accurately set the execution time for starting/finishing the fractionation in a preparative separation unit 16. A piping 17 may be placed so that the traveling time of sample components is sufficiently larger than the delay time of signals due to the signal transfer lag and other reasons. This can absorb the delay time, allowing the units to cooperate with each other at a correct timing.

1. An analyzing system comprising:
a commanding unit for sending a command; and an executing unit for, upon receiving the command, executing a processing, wherein the commanding unit computes a shift time which is a difference between a predetermined base-point time in the executing unit and an execution time of the processing for which the command is sent to the executing unit, and sends the computed shift time with the command for the processing to the executing unit, and the executing unit executes, at a point in time before or after the base-point time by the shift time, the processing indicated by the command received with the shift time.
