摘要

A first flow rate adjustment mechanism (18) and a second flow rate adjustment mechanism (28) are controlled by a flow rate control unit (62) so that a carrier gas flows through a first supply path (56) and a second supply flow rate (57) at a predetermined flow rate. The flow rate control unit (62) includes cell flow rate control means (66) for controlling the first flow rate adjustment mechanism (56) and the second flow rate adjustment mechanism (57) so that the flow rate of the carrier gas introduced into a sample cell (44) in a sparging state, which is a state where the carrier gas is supplied from the first supply path (56) into a syringe pump (4), and the flow rate of the carrier gas introduced into the sample cell (44) in a normal state, which is a state where the carrier gas is not supplied from the first supply path (56) into the syringe pump (4) become the same.
