Abstract: In the present invention, differences in liquid feed properties between liquid chromatographic devices are determined, a liquid feed time table that takes these differences into account is acquired by way of system changes, and flow control is performed by a pump. Furthermore, the liquid feed time table after the system changes is divided into a plurality of intervals, and instructions are sent to the pump after approximate calculations are performed. Thus, by efficiently performing system change processes, the same measurement results can be obtained in a plurality of different liquid chromatograph devices, regardless of the differences in liquid feed properties.
