Abstract
A preparative separation-purification system has controlling apparatus, which has a pump housing for pumping liquid. The apparatus also has a moving component for reciprocating in the pump housing so as to draw a liquid into the pump housing and discharge the liquid from the pump housing and a driving source for reciprocating the moving component. A setting unit is provided for setting a target liquid supply amount or a target amount which corresponds thereto. A unit amount memory unit is provided for storing a discharge amount of the reciprocating pump per a reciprocal movement of the moving component or a unit amount which is a value corresponding to the discharge amount. A computation unit is provided for computing the smallest multiple number of the unit amount which is equal to or larger than the target amount; and a motor controller for controlling the driving source.
