Title: FLOW CELL FOR OPTICAL MEASUREMENT
Abstract:
Provided is a flow cell for optical measurement with which it is possible to stabilize and accurately measure light from particles with respect to laser light imparted in a flow path. A substantially cuboid flow path block (20) comprising a transparent material is removably sandwiched between a fluid medium inflow block (21) and an outflow block (22), which constitute a pair, and light-absorption surfaces of the fluid medium inflow block (21) and outflow block (22) are pressed toward each of two end surfaces. A flow path (10) is provided along a central axis that passes between the two end surfaces of the flow path block (20), an optical window is removably provided to outer-side opening end parts (13a, b) of extension flow paths (12a, b) that run along the central axis, and the opening end parts (13a, b) are sealed. Inlet and outlet paths (35a, b) for the liquid medium are also provided along introduction axes that intersect the central axis near the outer-side opening parts (13a, b).
