Claim 0:
1. A liquid chromatographic system comprising:
an analysis flow path connected to at least one liquid sending pump having a liquid sending mode and through which liquid flows that is sent by the liquid sending pump;
a sample injector configured to inject a sample into the analysis flow path;
a separation column configured to separate the injected sample into components;
a detector configured to detect the separated components;
a computer circuit, executing a program, configured to:
specify as a system configuration a count and a connection structure of the liquid sending pumps connected to the analysis flow path;
store, for each of a plurality of different types of system configurations, a preset condition for detecting a liquid sending failure of the liquid sending pump based on the liquid sending mode of the at least one liquid sending pump;
determine the stored preset condition for the specified system configuration and the liquid sending mode of the at least one liquid sending pump; and
detect a liquid sending failure of the liquid sending pump using the determined preset condition.
