PROBLEM TO BE SOLVED: To provide a centrifugally pressure reducing concentrator capable of heating a great number of samples uniformly, while simplifying a device structure when electromagnetic induction by permanent magnets is used as a heat source.SOLUTION: The centrifugally pressure reducing concentrator includes: a rotating body 13 rotating around an axis of a vacuum chamber 12, as the center of rotation; and permanent magnets 16 that are provided outside the vacuum chamber, and which heat the rotating body by electromagnetic induction. At the rotating body, multiple inner circumferential container holders 23 are provided on an inner circumference 25a of which the center is a rotational axis of the rotating body, at circumferentially regular intervals. On an outer circumference 25b of the rotating body, there are provided a number of outer circumferential container holders 24 equal to twice the number of the installed inner circumferential container holders. An interval between the outer circumferential container holders circumferentially adjacent to each other is a wide interval 24a through which a radial direction line 13r of the rotating body, passing through the inner circumferential container holders, passes, and is a narrow interval 24b through which the radial direction line does not pass.SELECTED DRAWING: Figure 2 |
