Abstract

In order to remove dust attached to a filter member 40 to surely clean the filter member 40, an analysis apparatus 100 includes: a sample containing part 10 that contains a sample; the filter member 40 through which gas produced from the sample heated in the sample containing part 10 passes; and a gas flow path L 1 adapted to lead the gas having passed through the filter member 40 to an analyzer. In addition, the filter member 40 is formed in a tubular shape, and in one end part of the filter member 40, a gas lead-out port 40 a connecting to the gas flow path L 1 is formed. Further, it is configured that the gas passes through a side wall part 42 of the filter member 40 from outside to inside, and flows from the gas lead-out port 40 a to the gas flow path L 1.

First claim

1 . An analysis apparatus comprising:
a sample containing part that contains a sample; a filter member through which gas produced from the sample heated in the sample containing part passes; and a gas flow path adapted to lead the gas having passed through the filter member to an analyzer, wherein: the filter member is formed in a tubular shape, and in one end part of the filter member, a gas lead-out port connecting to the gas flow path is formed; and it is configured that the gas passes through a side wall part of the filter member from outside to inside, and flows from the gas lead-out port to the gas flow path.

2 . The analysis apparatus according to claim 1 , further comprising
a cleaning gas supply mechanism that supplies cleaning gas for cleaning the filter member to an inside the filter member from a cleaning gas supply port formed in the one end part of the filter member, wherein it is configured that the cleaning gas supplied by the cleaning gas supply mechanism passes through the side wall part of the filter member from inside to outside.

3 . The analysis apparatus according to claim 1 , wherein:
the filter member is provided above the sample; and the sample containing part has a tubular member that contains the filter member, from an lower end part to an upper end part of the filter member, as well as the sample, and is formed of a single member.

4 . The analysis apparatus according to claim 1 , wherein
the sample containing part has: a heating furnace main body that heats the sample; a lid body that is detachably attached to an upper part of the heating furnace main body, and holds the filter member as well as rotating around an axis along a direction of the attachment/detachment; and a removal assisting mechanism that is provided between the heating furnace main body and the lid body, and converts force applied to the lid body in a rotational direction to force in a vertical direction and assists removal of the lid body.

5 . An analysis apparatus comprising:
a sample containing part that contains a sample; a filter element through which gas produced from the sample heated in the sample containing part passes; an analyzer that analyzes the gas having passed through the filter element; and a cleaning gas supply path adapted to supply cleaning gas for cleaning the filter element to an inside the filter element from one end opening of the filter element.
