Abstract
A mobile phase temperature control device for a supercritical fluid apparatus is used in a supercritical fluid apparatus including a separation column, and includes a cartridge heater, a flow path portion and a first temperature sensor. The cartridge heater has a rod shape. The flow path portion is wound around the cartridge heater, and a mobile phase is guided to the separation column of the supercritical fluid apparatus by the flow path portion. The mobile phase is put in a supercritical state at least in the separation column. The first temperature sensor is attached to the flow path portion, and the temperature of the flow path portion is detected by the first temperature sensor.
