Abstract: A liquid chromatograph includes: a liquid meter that measures a liquid amount of a mobile phase stored in one or more mobile phase containers; and a notification unit that notifies an operator of the liquid amount of the mobile phase in each of the one or more mobile phase containers measured by the liquid meter. According to such a liquid chromatograph, when the operator replenishes the mobile phase to the mobile phase container, it is not necessary to visually measure the liquid amount of the mobile phase or manually input the value to the control device, so that it is possible to reduce the workload of the operator regarding the liquid amount management of the mobile phase.

Abstract: The automatic suitability determination system includes a check document storing part, a check document retrieving part, a determination test execution part, and a suitability determination part. The check document storing part stores suitability check documents. The check document retrieving part is configured to read out the suitability check document related to a determining target component of operational suitability from the check document storing part. The determination test execution part is configured to read information contained in the suitability check document read out by the check document retrieving part and to execute tests of suitability determination items specified in the suitability check document by making the determining target component of the operational suitability operate based on the information. The suitability determination part is configured to determine, based on results of the tests executed by the determination test execution part, suitability for the suitability determination items corresponding to the tests.
