摘要
An apparatus and method are disclosed for determining electrophoretic mobility using scattering light phase analysis comprising emitting a laser light along a path and transmitting a first portion of the laser light and reflecting a second portion of the laser light. The apparatus and method can also comprise deflecting one of the first and second portions of the laser in response to a drive signal, holding a sample to receive at least one of the first and second portions of the laser light under an electric field and output a composite light wave, outputting a photopulse signal based on the composite light wave, and measuring the electrophoretic mobility of the sample based on a phase shift analysis using cross-correlation of the photopulse signal with the drive signal.
