Title:
AUTOMATIC IMMUNOLOGICAL ANALYZER
Document Type and Number:
WIPO Patent Application WO/1998/018008
Kind Code:
A1
Abstract:
An automatic immunological analyzer, wherein reaction tube arrays are set between outer and inner circumferential edges of a reaction tube turret, and magnet-mounted pivotable magnet rings are provided therebetween. The effective B/F separation and agitation of a reagent of fine magnetic particles is carried out by making the positions of the reaction tubes and magnets stagger by one pitch in every one index time, and a photometric examination is then conducted by a chemiluminescence method. Since a method using a dedicated tip is employed for the dispensation of a sample and reagent, the tip is changed each time, so that mutual contamination does not occur. Dedicated pumps and nozzles are also used for an agitated liquid and an injected liquid.
