The flow cell and the fluorescent correlation spectrometry device which uses this

摘要

The detection territory 34 where focus P of the excited light R for the minute sample liquid is set, it expands vis-a-vis the passage 37,38 of the minute sample liquid, there is no uses wastefulness and the sample liquid. In addition, because of this, influence to the Brownian movement by the inner wall of the detection territory 34 is decreased. In addition, in order not to enter into the optical path of excited light R, lap the wall 34e of the detection territory 34 is formed, the refraction which it disperses and expects of excited light R is prevented. In addition, in degree of detection of minute sample liquid which is not identical, passage by the fact that you wash 37,38 and the detection territory 34, throughput it improves through the inlet and the outlet. Because of this, as the minute sample liquid is offered to detection efficiently, the flow cell which improves, and the fluorescent correlation spectrometry device which uses this are actualized the detection precision of fluorescent correlation spectrometry.
