  • Patent number: 8216516
    Abstract: An analytical system for performing centrifugal analysis on a working fluid with different components includes a uniform-dividing unit with a reduced cross section to divide the working fluid, a separating unit connected to the uniform-dividing unit, and a detecting unit. The detecting unit includes a detection compartment and a constant-quantity region connected to the separating unit through a separation channel. When rotating the uniform-dividing unit, the working fluid located at the uniform-dividing unit is transmitted to and separated by the separating unit, thereby causing one component of the working fluid to be separated from the other component and transmitted to the detection compartment through the constant-quantity region. With constant-quantity region, the detection compartment can be prevented from flushing by the excess of the separated component, and thus yield of product detection can be increased and different assays detection is carried out with a small sample volume at the same time.
