ABSTRACT:
A flow cell is provided which can detect scattered light more efficiently by fully utilizing the condensing angle of a condenser lens. A particle monitoring area M is formed within the flow cell by irradiating the area with laser light La, and scattered light Ls generated by particles contained in sample fluid passing through the particle monitoring area M is condensed by the condenser lens L so as to obtain information including diameter of the particles, and inner walls of the flow cell are shaped or arranged such that the scattered light Ls is condensed in a state where the condensing angle θ of the condenser lens L is fully utilized.
