The particles also disperse as they advect downstream. We
quantify the dispersion as the standard deviation width of a
Gaussian distribution ¨®. We determine the total dispersion width
¨®T as the square root of the sum of individual variances.44 The
individual sources of measured dispersion include Brownian
diffusion, the effects of sidewall roughness, and finite resolution
of particle imaging. We have specifically neglected any electrostatic
effects due to repulsion of the thin electric double layers.
