Abstract: A first attachment portion to which a packed column is attachable and a second attachment portion to which a chip column is attachable are housed in a column oven. Designation of a temperature of the column oven is received by a designated temperature receiver. In a case in which the chip column is not attached to the second attachment portion, an upper limit temperature of the column oven is set to a first temperature by a setter. An upper limit temperature of the column oven is set to a second temperature lower than the first temperature in a case in which the chip column is attached to the second attachment portion. A temperature of the column oven is adjusted to a received temperature by a temperature adjuster in a case in which the received temperature is equal to or lower than an upper limit temperature.
