Measurement of Dispersion and Separation Resolution. We determine the separation resolution by measuring the particle position distribution in the expanded section. The measurements are made from an ensemble average of 100 epifluorescent images of particle streams undergoing separation. We average the image intensities along the x-axis to obtain the particle intensity distributions as a function of z. An exemplary particle intensity with a bimodal Gaussian fit is shown in Figure 3. We obtain the dispersion widths (s1,s2) and the particle stream centers (z1,z2) from the Gaussian fit. |
