Abstract
Liquid sent by a liquid sending pump flows through an analysis flow path. A sample is injected into the analysis flow path. A separation column is provided in the analysis flow path. A sample injected in the separation column is separated into components, and sample components obtained by separation are detected by a detector. The number of liquid sending pumps and a connection structure of the liquid sending pumps connected to the analysis flow path are specified by a system configuration specifier as a system configuration. A condition for detecting a liquid sending failure in a liquid sending pump that is preset for each type of system configuration is held by a condition holder. A condition corresponding to a system configuration is determined from conditions held by the condition holder. A liquid sending failure in a liquid sending pump is detected with use of the determined condition.
