摘要： In a chromatograph, a mobile phase is supplied to any of a plurality of columns by a mobile phase supplier, and a sample is supplied to the column by a sample supplier. The sample that has passed through the column is detected by a detector. In a chromatographic control device, a flow rate of the mobile phase for the analysis with use of the column is registered by a flow rate registrar in association with column specifying information for specifying each column. The flow rate of the mobile phase registered in association with a selected column is acquired from registered content of the flow rate registrar. The chromatograph is controlled such that the analysis is performed by an analysis controller while the mobile phase is supplied to the selected column with use of the selected column and the flow rate of the mobile phase acquired by a flow rate acquirer.
