Patent ID: 7678576

Claim:
A chemical analysis apparatus comprising: a retaining disc rotatable around a rotating axis passing through a center; a detachable inspection cartridge retained in said retaining disc; said inspection cartridge having a base plate including a container and a flow path formed by a concave portion, and a cover covering said container and said flow path; and a liquid solution being moved to the container in an outer peripheral side with respect to said rotating axis from the container in an inner peripheral side with respect to said rotating axis via said flow path, by utilizing a centrifugal force generated by a rotation of said retaining disc, wherein the chemical analysis apparatus is provided with an agitating means for agitating the liquid solution within said container, and a waste fluid storage container storing a waste fluid, wherein said agitating means has an air reservoir container connected to a flow path connected to an outlet of said container, the liquid solution within said container moves into said air reservoir container at a time when a centrifugal force is applied, and the liquid solution moving into said air reservoir container is returned to said container at a time when the centrifugal force is not applied, and wherein said air reservoir container is provided on an inner peripheral side of a waste fluid flow path between said container and said waste fluid storage container.
