Abstract

A sample holder unit for a single-crystal X-ray structure analysis apparatus that quickly, surely and easily performs structure analysis with a crystalline sponge, the structure analysis inclusive of an operation of attaching a sample soaked in the crystalline sponge thereto, even if having no specialized knowledge, is provided. There are provided a sample holder, and an applicator comprising an opening 302 and a storing space in which the sample holder is stored, and a pull-out prevention part that selectively prevents and releases the sample holder stored in the storing space from being pulled out from the opening 302 , wherein the pull-out prevention part comprises an operation part that releases pull-out prevention thereof in a state where the sample holder stored in the applicator is attached to the goniometer.

First claim

1 . A sample holder unit comprising a sample holder used in a single-crystal X-ray structure analysis apparatus, and an applicator in which the sample holder is stored,
the sample holder comprising: a base part attached to a goniometer in the single-crystal X-ray structure analysis apparatus, the base part formed to have a sample introduction structure into which a sample to be soaked in a porous complex crystal is introduced; and a holding part that holds the porous complex crystal capable of soaking the sample in a plurality of fine pores formed therein, the holding part formed on the base part, and the applicator comprising: an opening and a storing space in which the sample holder is stored, and a pull-out prevention part that selectively prevents and releases the sample holder stored in the storing space from being pulled out from the opening, wherein the pull-out prevention part comprises an operation part that releases pull-out prevention thereof in a state where the sample holder stored in the applicator is attached to the goniometer.

2 . The sample holder unit according to claim 1 ,
wherein the applicator further comprises a separation mechanism to separate the sample holder therefrom by releasing the pull-out prevention with the operation part.

3 . The sample holder unit according to claim 2 ,
wherein the separation mechanism comprises a seal part with which a contact surface between the applicator and the sample holder stored therein is airtightly maintained.

4 . The sample holder unit according to claim 3 ,
wherein the pull-out prevention part prevents the sample holder from being pulled out therefrom in a state of pressing the sample holder to the seal part.

5 . The sample holder unit according to claim 1 ,
wherein the pull-out prevention part that protrudes toward the opening of the applicator comprises a swing lever that prevents the sample holder from being pulled out therefrom.

6 . The sample holder unit according to claim 1 ,
wherein the pull-out prevention part that protrudes toward the opening of the applicator has a shape that prevents the sample holder from being pulled out therefrom.

7 . The sample holder unit according to claim 6 ,
wherein the pull-out prevention part has an inclined surface at an end of a sliding surface of the pull-out prevention part with the sample holder.

8 . The sample holder unit according to claim 6 ,
wherein the applicator has a pair of parallel guide rails provided at both side portions of the applicator, and the pull-out prevention part slides to be engaged with the pair of parallel guide rails.

9 . The sample holder unit according to claim 6 ,
wherein the applicator has a pair of parallel guide rails provided at both side portions of the applicator; the pull-out prevention part comprises engagement parts that slide to be engaged with the pair of parallel guide rails; and the pair of parallel guide rails and the engagement parts each whose cross-section is U-shaped are formed.

10 . The sample holder unit according to claim 2 ,
wherein the pull-out prevention part that protrudes toward the opening of the applicator comprises a swing lever that prevents the sample holder from being pulled out therefrom.

11 . The sample holder unit according to claim 3 ,
wherein the pull-out prevention part that protrudes toward the opening of the applicator comprises a swing lever that prevents the sample holder from being pulled out therefrom.

12 . The sample holder unit according to claim 4 ,
wherein the pull-out prevention part that protrudes toward the opening of the applicator comprises a swing lever that prevents the sample holder from being pulled out therefrom.

13 . The sample holder unit according to claim 2 ,
wherein the pull-out prevention part that protrudes toward the opening of the applicator has a shape that prevents the sample holder from being pulled out therefrom.

14 . The sample holder unit according to claim 3 ,
wherein the pull-out prevention part that protrudes toward the opening of the applicator has a shape that prevents the sample holder from being pulled out therefrom.

15 . The sample holder unit according to claim 4 ,
wherein the pull-out prevention part that protrudes toward the opening of the applicator has a shape that prevents the sample holder from being pulled out therefrom.

16 . The sample holder unit according to claim 7 ,
wherein the applicator has a pair of parallel guide rails provided at both side portions of the applicator, and the pull-out prevention part slides to be engaged with the pair of parallel guide rails.

17 . The sample holder unit according to claim 7 ,
wherein the applicator has a pair of parallel guide rails provided at both side portions of the applicator; the pull-out prevention part comprises engagement parts that slide to be engaged with the pair of parallel guide rails; and the pair of parallel guide rails and the engagement parts each whose cross-section is U-shaped are formed.
