Abstract:
A flow cell apparatus, useful in an apparatus for measuring particles suspended in a liquid, comprises a sample liquid, supply device, a sheath liquid supply device, a flow cell which has a flow passage passing through a transparent measuring portion, and a nozzle for causing the sample liquid, from the supply device to flow in the flow passage of the flow cell. The nozzle has at least one discharge port which is disposed in the flow passage in a spaced relation from the inner wall of the flow cell flow passage. The sheath liquid supply device causes the sheath liquid to flow around the nozzle discharge port and surround the sample liquid flow to form a sheath flow. The flow passage of the flow cell and the nozzle are so formed as to ensure a sample liquid flow of a fixed width through the measuring portion. A stable sample flow having a fixed width can be formed in the measuring portion even when the flow is at a high velocity, and particles in the sample liquid can efficiently be photographed with high accuracy.
