Abstract:
1. A flow cell device comprising: a flow cell body, having a lower surface, and disposed in contact of said lower surface with a sensing surface for detecting reaction of sample; at least two flow channels, formed in said flow cell body, for flow of said sample; each of said flow channels including a fluid passageway, formed in said lower surface, for flow of said sample in contact with said sensing surface, and two end cavities, formed in an upper surface of said flow cell body and open therein, to extend from ends of said fluid passageway; at least one flow channel set constituting said at least two flow channels, said flow channels being arranged adjacent to one another as viewed in a direction of said flow, disposed to extend in said direction of said flow, fluid passageways of said flow channels being overlapped partially on one another in a predetermined direction of said flow cell body; wherein each of said fluid passageways extends to intersect with a reference straight line extending in said predetermined direction, and wherein a measurement point of each of said fluid passageways is disposed at a point on the reference straight line.
