| description | A fluidic system (10) and method are provided for precisely controlling fluid flow through a flow cytometer (12), with infinitely variable flow rates and sample fluid core sizes, by independently controlling fluid flow rates via fluid pump speeds. In one embodiment, the system uses two cyclic positive-displacement pumps (36, 38) and three valves (40, 42, 44), and operates via the precise control of the pumps (36, 38) along with coordinated operation of the valves (40, 42, 44). In another embodiment, the system uses constant-flow positive-displacement pumps, without need for valves associated with cyclic pumps. The fluid flow rates and core sizes may be determined or selected by correlating pump operating parameters to fluid flow rate. |
