A liquid chromatograph includes a liquid chromatograph unit that has a pump sending an eluent to a detector and a control unit that controls the liquid to be sent by the pump based on a predetermined time table. The control unit stores an elution response of the liquid chromatograph unit which is obtained when a predetermined command value is input and another elution response which is obtained when the same command value is input to another liquid chromatograph. The time table is converted in the control unit based on the elution response and the other elution response to obtain respective elution profiles. In this manner, even when a measuring method related to another liquid chromatograph is used, it is possible to provide a liquid chromatograph capable of obtaining measurement results which are the same as those obtained when the measuring method is used in the other liquid chromatograph.

A method of generating smear quality control information according to an embodiment may include: obtaining a plurality of image data from a plurality of smears, respectively; obtaining, from the plurality of image data, feature values each of which reflects a staining state of each smear; and generating quality control information based on the feature values.
