Abstract: PURPOSE:To falsely perform a simultaneous parallel processing by using a simple computer by connecting an interruption signal line between a CPU to control an analysis operation and a host computer based on sequence control instructions stored comprehensively in a sequence table memory. CONSTITUTION:The sequence control instructions are transferred comprehensively from the host computer 6 to the sequence table memory 8, and the CPU4 reads out the control instruction in the memory 8 at every step, and executes the instruction on an analyzer 2. During that time, the computer 6 is not requested to make access to the CPU4, and is released from control for the analyzer 2, then, it can execute another processing. And when the execution of all of the control instructions are completed, the CPU4 outputs an interruption signal to the computer 6 via the interruption signal line 10, and the computer 6 sends a new control instruction to the memory 8. In such a way, it is possible to perform the simultaneous parallel processing falsely by the simple computer such as a personal computer, and to increase the working time of the analyzer essentially.
