Liquid chromatograph 100 for performing a plurality of analyses according to a schedule table includes: mobile phase switching sections 15, 16 for switching a plurality of mobile phases to select a mobile phase to be used in analysis; column switching sections 31, 33 for switching a plurality of columns 32a-32f to select a column to be used in analysis; and control section 60 including memory 61 for storing an equilibration time of each of the plurality of columns 32a to 32f and an equilibration controller 66 for controlling column equilibration. If used columns or used mobile phases are different between two consecutively executed analyses, equilibration controller 66 equilibrates a column used in the later of the two analyses over an equilibration time read out from memory 61.
