Capillary array unit and electrophoretic device comprising the same

摘要: A capillary array comprises a plurality of capillaries and two holding substrates sandwiching at least part the to generally planarly. In one substrate, there are formed detection apertures for passing light emitted by application from samples be measured. Especially, these so arranged correspond respective thereby provide light-passing areas through which passes, light-shielding interposed between blocking light. With areas, reflected surfaces can blocked improve SN ratio realize highly precise detection.
