1. A suppressor device for an ion chromatograph, provided between a separation column and a detector of an ion chromatograph, comprising:
an electrodialysis suppressor that includes a first flow path to which an eluate flowing from the separation column is supplied, a second flow path to which a regeneration liquid is supplied and an ion exchange membrane provided between the first flow path and the second flow path and an electrode to which a voltage is applied; and
a power supply circuit that applies a voltage to the electrode, wherein
the power supply circuit is turned off in a case in which it is detected that the
eluate is not supplied to the first flow path of the electrodialysis suppressor.
