  • Supercritical fluid device
    Patent number: 10180412
    Abstract: Provided is a supercritical fluid device equipped with a back pressure regulator for creating a pressurized state in which a mobile phase in a separation/extraction unit of an analysis flow passage is kept in a supercritical fluid state. One end of a pipe is connected to an outlet side of the back pressure regulator, and the other end of the pipe is open to the atmosphere. A heating unit is provided on the pipe, and the heating unit includes a plurality of electrically independent heaters arranged on mutually different portions of the pile along the pipe. A power supply controller is connected to the heaters, and the power supply controller is configured to supply heating power to one or more heaters selected among the plurality of heaters, but to not supply heating power to the other heaters.
