PROBLEM TO BE SOLVED: To provide a sublimation refining apparatus capable of increasing sublimation efficiency further even when not only a crude material having high thermal stability but also a crude material having low thermal stability are used as samples.SOLUTION: Provided is a sublimation refining apparatus having a sublimation pipe, a vacuum pump and piping connecting the sublimation pipe and the vacuum pump. When an end part of the sublimation pipe, further from the vacuum pump, is defined as A and a connection part of the piping and the vacuum pump is defined as C, conductance (K) from A to C is 0.01 m/sec or more. |
