摘要： PURPOSE: To perform stable temp. control by providing an annular space housing a separation column in an oven main body housing the separation column wound in an annular shape and introducing cooled N2 gas into the oven main body as a temp. control medium. CONSTITUTION: A separation column 4 wound in an annular shape is housed in the internal space 3 of an oven main body 2 formed into a ring shape. The branch cooling medium pipes 51-53 branched from the cooling medium introducing pipe 5 passing through a Dewar vessel 7 storing liquid N2 are connected to the lower part of the main body 2 to communicate with the space 3. The introducing pipe 5 receives the supply of N2 gas from the outside to introduce the N2 gas into the vessel 7. The introducing pipe 5 is allowed to communicate with the bypass 5a led out of the upper part 7a of the vessel 7 in the front stage thereof to also introduce the N2 gas gasified in the vessel 7 to efficiently form the N2 gas to introduce the same into the space 3. A piezoelectric valve 9 adjusts the flow rate of the N2 gas introduced into the introducing pipe 5 from the outside. A temp. controller 10 sends out control output to the valve 9 on the basis of the temp. data from a temp. sensor 11.
