Embodiment

For making the object of the utility model embodiment, technical scheme and advantage clearly, below in conjunction with the accompanying drawing in the utility model embodiment, technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.

The utility model provides a kind of rotary sampling device for trace quantity detector, see Fig. 1 to Fig. 6, comprising:

Swingle 1, sample introduction main body 2 and swingle support 3, wherein, described sample introduction main body 2 is positioned at described swingle support 3, and described swingle 1 is through described swingle support 3 and described sample introduction main body 2, and fixed by securing member 5 and described sample introduction main body 2, described swingle 1 is rotatable.

Alternatively, swingle 1 heats by rotating the heating member 4 making the sample in described sample introduction main body 2 be fixed on described swingle support 3 and volatilizees.

Alternatively, as shown in Figure 2, securing member 5 can be one or more trip bolt, and swingle 1 also has the screw that quantity and size match, and sees Fig. 3.

Alternatively, the side of sample introduction main body 2 can be semi-surface, as Fig. 4.Certainly, sample introduction main body 2 also can be other shapes, if side is polygon etc., only need meet sample introduction main body 2 no-float both when being heated by heating member 4.

Wherein, sample introduction main body 2 can be sampled in several ways, both can directly make the direct wiping of sample to the surface of sample introduction main body 2 as sampler, also at surface coverage one deck test paper, can make sample by wiping to test paper surface.
