Chemical analysis apparatus and chemical analysis cartridge

A chemical analysis cartridge comprising:

• a base plate having a container and a flow path formed by a concave portion;
• 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 a rotating axis perpendicular to said base plate 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 around said rotating axis,
• wherein chemical analysis cartridge 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.

A chemical analysis cartridge for use in a chemical analysis apparatus having a retaining disc rotatable around a rotating axis, the chemical analysis cartridge having an inner peripheral side adapted to face towards the rotating axis of the retaining disc of the chemical analysis apparatus and an outer peripheral side adapted to face away from the rotating axis of the retaining disc of the chemical analysis apparatus, and comprising:

• a base plate having an eluting fluid recovery container, a waste fluid storage container for storing a waste fluid and a waste fluid flow path formed by a concave portion connecting the eluting fluid recovery container and the waste fluid storage container;
• a cover covering the eluting fluid recovery container, the waste fluid storage container and the waste fluid flow path,
• wherein a liquid eluting solution is moved in the eluting fluid recovery container from the inner peripheral side of the eluting fluid recovery container to the outer peripheral side of the eluting fluid recovery container by utilizing a centrifugal force generated by rotation of the chemical analysis cartridge around the rotating axis;
• and
• agitating means comprising an air reservoir container connected to an inner peripheral side of the waste fluid flow path between the eluting fluid recovery container and the waste fluid storage container, and configured such that the liquid eluting solution within the eluting fluid recovery container moves into the air reservoir container at a time when a centrifugal force is applied, and the liquid eluting solution within the air reservoir chamber is returned to the eluting fluid recovery container at a time when the centrifugal force is not applied.
