Hydrodynamic focusing devices
First Claim
1. An analysis system comprising:
- a micro-fluidic device;
a hydrodynamic focusing system of the micro-fluidic device, the hydrodynamic focusing system containing;
a micro-fluidic inlet channel to convey a process flow;
a plurality of micro-fluidic focusing channels to each convey one of a plurality of focusing flows;
a focusing manifold coupled with the inlet channel at an inlet port and with the plurality of focusing channels at a plurality of focusing channel ports to focus the process flow by contacting at least three sides of the process flow with the plurality of focusing flows; and
a micro-fluidic outlet channel coupled with the focusing manifold at an outlet channel port to convey the combined focused process flow and focusing flow from the focusing manifold;
an analysis device to analyze a portion of the focused process flow conveyed in an interrogation region of the micro-fluidic outlet channel.
