Automatic response/light measurement device and method therefor
First Claim
1. An automatic response/light measurement device comprising:
- a container group in which two or more reaction containers and a plurality of liquid housing parts are arranged, the liquid housing parts containing;
one or more reaction solutions usable for various reactions, one or more magnetic particle suspensions in which magnetic particles able to capture a target compound are suspended, one or more samples containing the target compound, and one or more solutions for separating and extracting the target compound; and
a nozzle head, comprising;
a suction-discharge mechanism able to suction and discharge gases;
two or more nozzles connected to the suction-discharge mechanism and movable relative to the container group, wherein a dispensing tip is detachably mountable to each of the nozzles so that suction and discharge of gases by the suction-discharge mechanism causes suction and discharge of liquids by the dispensing tips;
a magnetic force part including a magnet able to apply a magnetic field to the dispensing tips so that the magnetic particles are adsorbed to respective inner walls of the dispensing tips mounted on said nozzles, and to remove the magnetic field from the dispensing tips so that the magnetic particles are resuspended;
a measurement mount from which two or more coupling ends extend, each of the coupling ends having a light guide portion, wherein the measurement mount;
defines a movement path along which the coupling ends are arranged, andis movable relative to the container group to simultaneously directly or indirectly join the coupling ends with respective apertures of the reaction containers so that the light guide portions of the coupling ends are optically connected with respective interiors of the reaction containers; and
a measuring device including one or more measuring ends each having a light guide portion that is sequentially optically connectable with the respective light guide portions of the coupling ends so that the measuring device is able to receive light via the one or more measuring ends based on optical states within the respective reaction containers;
wherein the suction-discharge mechanism and the magnetic force part, in combination, are operable to;
separate the target compound from each of the one or more samples, anddischarge the separated target compound in one or more of the reaction containers with at least one of the one or more reaction solutions;
andwherein, upon the coupling ends being simultaneously directly or indirectly joined with the respective apertures of the reaction containers, the one or more measuring ends are movable along the movement path and relative to the measurement mount to sequentially optically connect the light guide portion of each of the one or more measuring ends with the respective light guide portions of the coupling ends so that the measuring device receives light sequentially from within each of the respective reaction containers.
