1. A method of sorting particles within a sample, with use of a flow cytometer, the method comprising: (a) analyzing a sample having a plurality of particle populations with a flow cytometer; (b) obtaining a parameter plot from the flow cytometry analysis of step (a); (c) defining a coincidence acceptance gate in the parameter plot of step (b), wherein the coincidence acceptance gate identifies a non-target particle population that may be accepted with a target particle in a subsequent sort analysis; and (d) processing the sample through a sort analysis.
