Fractionating and refining device

A fractionating and refining device comprising:

• a solution sending device for supplying a solution including a fractionated target component from a tip end of a solution sending flow path;
• a gas supply flow path for supplying gas from a tip end thereof;
• a collecting vessel for collecting solid material of the fractionated target component, said collecting vessel comprising a lid and a vessel main body having a bottom,
• the lid closing an opening portion of the collecting vessel main body and being able to be opened and closed, and
• the lid including a solution inlet to which the tip end portion of the solution sending flow path is connected and through which the solution is supplied into the vessel main body, a gas inlet to which the tip end portion of the gas supply flow path is connected and through which the gas from the gas supply flow path is supplied into the vessel main body, and a gas discharge port connecting an inside and an outside of the vessel main body;
• a warming mechanism for warming the collecting vessel to such a temperature as to facilitate evaporation of a solvent in the solution in the collecting vessel;
• and
• a probe formed by integrating the tip end portion of the solution sending flow path and the tip end portion of the gas supply flow path with each other, wherein the solution inlet and the gas inlet in the lid are disposed in positions respectively corresponding to the tip end portion of the solution sending flow path and the tip end portion of the gas supply flow path integrated in the probe so that the tip end portion of the solution sending flow path and the tip end portion of the gas supply flow path are respectively connected to the solution inlet and the gas inlet in the lid when the probe is mounted to the lid,
• wherein the lid has a recessed portion, in which the solution inlet and the gas inlet are open, for mounting the probe therein to detachably connect to detachably place an end surface of the tip end portion of the solution sending flow path in contact with an end surface of the solution inlet and to detachably place an end surface of the gas supply flow path in contact with an end surface of the gas inlet.
