1. A method of positioning agents in a fluid flow, the method comprising:
- providing a chamber having a porous substrate;
flowing a first fluid flow through a first fluid port and through the porous substrate in the chamber, wherein the first fluid flow contains agents;
flowing a second fluid flow through the chamber, the second fluid flow at least partially surrounding the first fluid flow to direct the first fluid flow and any agents contained therein toward a central portion of the porous substrate;
positioning the agents on the central portion of the porous substrate; and
reversing flow through the first fluid port to move any agents positioned on the porous substrate out of the chamber in central streamlines that exit the chamber through the first fluid port.
