摘要：A flow cell for analysis of particles in a sample fluid buffered by sheath fluid hasa sample inlet to receive the sample fluid and a sheath inlet for receiving the sheath fluid.The sample fluid flows in a flow direction from the sample inlet past an examinationregion to an outlet. A flow distributor is positioned between the sheath inlet and the

examination region for distributing the sheath fluid ranging in a first directionsubstantially paralleled to the flow direction to the second direction substantiallyperpendicular to the flow direction. The distribution of the sheath fluid at the output ofthe distributor is vortex-free over a wide range of input directions and input chambergeometries. It eliminates the creation of vortices that could cause mixing and instabilityof the sample fluid in the examination area and allows greater freedom in shaping thefluid system for optimal hydrodynamic focusing.
