Patent ID: 8513026

Claim:
A vessel for sample decomposition, comprising; a reaction vessel having a connection portion to be combined with a collection tube thereon; and the collection tube composed of an intermediate tube, an inverse U-shape tube, and a collection tube cover, wherein the intermediate tube has a reaction vessel connection portion at the lower portion to be connected with the upper portion of the reaction vessel, an inverse U-shaped tube connection portion and a collection tube cover connection portion on the outer side and the inner side at the upper portion, respectively, and a tube formed to allow a gas produced in the reaction vessel to flow to the inverse U-shaped tube, the inverse U-shaped tube has an intermediate tube connection portion to be connected with the inverse U-shaped connection portion of the intermediate tube, at the lower portion, to be combined in an inverse U-shape, predetermined-sized holes are formed above the intermediate tube connection portion, the collection tube cover is combined with the intermediate tube by the collection tube cover connection portion to cover the inverse U-shaped tube, and a gas outlet is formed at the upper portion of the collection tube cover to allow air to pass therethrough.
