Liquid chromatograph

A liquid chromatograph comprising:

• one or more mobile phase containers each having a respective liquid meter;
• one or more pumps each connected to one of the one or more mobile phase containers;
• a correspondence relationship storage unit configured to store, for each of the one or more pumps, a correspondence relationship between an identifier of the pump and an identifier of a mobile phase container connected to the pump among the one or more mobile phase containers;
• a batch table storage unit configured to store a batch table in which a set of analyses and an order for executing the analyses are defined, the set of analyses including analysis conditions, each of the analysis conditions including information regarding which mobile phase and a pump are to be used therein;
• a predicted cumulative amount calculation unit configured to calculate, based on the correspondence relationship and the batch table, for each of the one or more mobile phase containers, a predicted cumulative amount of mobile phase that will be used in the set of analyses;
• and
• a notification unit configured to notify an operator of a fact that a liquid amount of a mobile phase is below the predicted cumulative amount when the liquid amount of a mobile phase measured by the liquid meter is below the predicted cumulative amount for at least one of the one or more mobile phase containers,
• wherein, in a case where the liquid amount of the mobile phase measured by the liquid meter is below the predicted cumulative amount for at least one of the one or more mobile phase containers, the notification unit notifies up to which analysis among the set of analyses can be executed in addition to a fact that the liquid amount of the mobile phase measured by the liquid meter is below the predicted cumulative amount.
