Claim Text:
1. A method of separating, detecting and determining a size of each of a plurality of particles in a fluid, comprising: compelling said fluid to flow through a fluid channel such that larger particles of said plurality of particles travel through said fluid channel faster than smaller particles of said plurality of particles; illuminating a detection zone of said fluid channel substantially uniformly across an entire cross section of said fluid channel such that each of said plurality of particles passes through illumination light upon passing through said detection zone; detecting each of said plurality of particles based on corresponding responses to said illuminating to determine a time that each of said plurality of particles passes through said detection zone; and determining a size of each of said plurality of particles based on said time that each of said plurality of particles passes through said detection zone, wherein said detection comprises quantification of said plurality of particles, and wherein said quantification is quantification by analyzing aggregate signals to correlate said aggregate signals with a quantity of particles in said plurality of particles.
