Abstract

An analytical tool for use in analysis of a sample is provided. The analytical tool includes a first unit and a second unit. The first unit has an analysis portion where analysis is performed. The second unit, configured to be coupled with the first unit, has a liquid reservoir for confining a particular liquid used for the analysis of the sample. When the first unit and the second unit are coupled, a fluid passage for conducting the particular liquid from the liquid reservoir into the first unit is formed by only a part of the first unit, or only a part of the second unit, or a combination of respective parts of the first unit and the second unit.

First claim

1 . An analytical tool comprising:
a first unit including an analysis portion for analyzing a sample; and a second unit configured to be coupled with the first unit and including a liquid reservoir for confining a particular liquid used for the analyzing of the sample, wherein a fluid passage for conducting the particular liquid from the liquid reservoir into the first unit is formed in the analytical tool with the first unit and the second unit coupled to each other, the fluid passage being provided by only a part of the first unit, or only a part of the second unit, or a combination of respective parts of the first unit and the second unit.

2 . The analytical tool according to claim 1 , wherein the second unit includes a sealing member that seals the liquid reservoir and is breakable for forming the fluid passage.

3 . The analytical tool according to claim 1 , wherein the first unit includes a sample collecting portion for taking the sample in.

4 . The analytical tool according to claim 3 , wherein the sample is moved in the sample collecting portion by capillary action.

5 . The analytical tool according to claim 1 , wherein the analytical tool is configured as a disposable tool.

6 . The analytical tool according to claim 1 , wherein the analytical tool is configured for use in analysis by electrophoresis, and the analysis portion comprises a capillary tube.

7 . The analytical tool according to claim 6 , further comprising a cylindrical electroconductive member having an inner surface and an outer surface, the inner surface defining a voltage application passage, the outer surface being exposed to an outside.

8 . The analytical tool according to claim 7 , wherein the cylindrical electroconductive member is provided in the second unit.

9 . An analytical system comprising:
an analytical tool of claim 1 ; and an analytical device to which the analytical tool is mounted.

10 . The analytical system according to claim 9 , wherein the analytical device is configured to perform pressure control for realizing liquid flow relative to the fluid passage.
