Abstract
A liquid chromatograph control system for controlling an operation of a liquid chromatograph which uses a mobile phase composed of a mixture of solvents and which has the function of performing a gradient analysis while temporally changing the mixture ratio of the solvents. The system initially requests a user to set a basic gradient profile (Step S), and subsequently, to set the number of steps to change the mixture ratio of the mobile phase at the beginning and/or at the end of the gradient process as well as the amount of change in the mixture ratio per step (Step S). After that, based on the possible combinations of the mixture ratios of the mobile phase at the beginning and at the end of the gradient process computed from the contents of information entered in the previous steps, a plurality of gradient profiles corresponding to those combinations are created (Step S).
