Abstract

An adsorption pump includes a housing, a movable part, and an adsorption part. The housing has inlet and outlet ports for a sample. The movable part is at least partly located inside the housing. The adsorption part is located inside the housing.

First claim

The invention claimed is:

1. An adsorption pump comprising:
a housing having an inlet port and an outlet port for a sample;
a movable part at least partly located inside the housing; and
an adsorption part located inside the housing;
wherein the absorption part is located in the movable part, and
wherein the movable part includes an impeller including a blade.

2. The adsorption pump according to claim 1 , wherein the adsorption part comprises nanofibers.

3. The adsorption pump according to claim 2 , wherein the adsorption part is located in a region facing the inlet port.

4. The adsorption pump according to claim 2 , further comprising a removal part configured to remove, from the adsorption part, a chemical substance adsorbed on the adsorption part.

5. The adsorption pump according to claim 4 , wherein the removal part comprises a heating part configured to heat the adsorption part.

6. The adsorption pump according to claim 5 , wherein the heating part includes:
a first electrode;
a second electrode; and
conductive nanofibers electrically coupled to each of the first electrode and the second electrode.

7. The adsorption pump according to claim 5 , wherein the heating part is made of a conductive thin film having a meandering shape.

8. The adsorption pump according to claim 1 , wherein the adsorption part is fixed to the impeller.

9. The adsorption pump according to claim 8 ,
wherein the impeller has a blade surface from which the blade projects, and
wherein the adsorption part is fixed to the blade surface of the impeller.

10. The adsorption pump according to claim 8 ,
wherein the impeller includes a plurality of blades including the blade,
wherein the impeller has a blade surface from which the plurality of blades projects, and
wherein the adsorption part is fixed to the blade surface of the impeller surface between the plurality of blades.
