Abstract

In order to surely discharge dust produced in a sample containing part 10 , the present invention is adapted to include: a dust introduction part 30 that has a through-hole 3 a formed penetrating in a vertical direction and introduces dust produced in the sample containing part 10 into the through-hole 3 a ; a dust containing part 43 that contains the dust discharged through the through-hole 3 a ; and a dust discharge path 41 a of which one end is connected to the dust introduction part 30 to communicatively connect to the through-hole 3 a and the other end is connected to the dust containing part 43 , in which the dust discharge path 41 a is linearly formed along the vertical direction from the one end to the other end.

First claim

1 . An analysis apparatus that heats a sample in a sample containing part and analyzes gas produced thereby, the analysis apparatus comprising:
a dust introduction part that has a through-hole formed penetrating in a vertical direction and introduces dust produced in the sample containing part into the through-hole; a dust containing part that contains the dust discharged through the through-hole; and a dust discharge path of which one end is connected to the dust introduction part to communicatively connect to the through-hole and the other end is connected to the dust containing part, wherein the dust discharge path is linearly formed along the vertical direction from the one end to the other end.

2 . The analysis apparatus according to claim 1 , comprising
an up/down movement mechanism adapted to integrally move up or down the dust introduction part, the dust discharge path, and the dust containing part.

3 . The analysis apparatus according to claim 1 , comprising:
a supporting part that supports the dust introduction part; and
a driving part that has a shaft member connected to the supporting part and moves up or down the supporting part, wherein
the shaft member is arranged separately from the dust introduction part in a horizontal direction by a predetermined distance.

4 . The analysis apparatus according to claim 1 , wherein
the through-hole is formed in a rotating body shape.

5 . The analysis apparatus according to claim 1 , further comprising
an open/close mechanism that is provided in the dust discharge path and switches an open/close state of the dust discharge path.

6 . An analysis apparatus that heats a sample in a sample containing part and analyzes gas produced thereby,
the analysis apparatus comprising a dust introduction part that has a through-hole formed penetrating in a vertical direction and introduces dust produced in the sample containing part into the through-hole, and being configured to create a substantially uniform flow from the sample containing part toward the through-hole to discharge the dust through the through-hole.

7 . The analysis apparatus according to claim 3 , wherein: the driving part further has a driving part main body into or out of which the shaft member moves;
the shaft member moves into the driving part main body, and thereby the dust introduction part moves in a direction to block a downward opening formed in the sample containing part; and the shaft member moves out of the driving part main body, and thereby the dust introduction part moves in a direction to open the opening.
