Abstract
A liquid sending system includes a plurality of liquid sending pumps that operate independently from one another and send a mobile phase into a common flow path, a pressure sensor for detecting a liquid sending pressure in the flow path, and a liquid sending failure detector configured to detect a liquid sending failure caused by any of the plurality of liquid sending pumps by periodically acquiring a liquid sending pressure detected by the pressure sensor and detecting a fluctuation of the liquid sending pressure associated with a driving period of each of the plurality of liquid sending pumps.
