    • ELS detection signal data may be analysed in a temporal ordering other than chronological. Electrochemical phenomena, e.g. electrode polarization and electrolysis, can be detected and the measured electrophoretic mobility values corrected. Corrections may be determined by determining particle motion deviating from an assumption that the electric field strength is not reduced due to electrochemical phenomena. Both laser Doppler electrophoresis (LDE) and phase analysis light scattering data analysis (PAL) methods may be applied to the same scattered light signal. A Doppler shift frequency distribution of the scatter light may be calculated using a modified Fourier transformation without resolution limit imposed by the electric field frequency. A reference beam configuration may employ acousto-optic modulators 514,540 as attenuator. A cross-beam configuration may have the detector out of the plane of the beams. Electrophoretic mobilities may be measured in low polarity / high ionic strength media, and of particles with low surface charge.

    • An apparatus and method to obtain electrophoretic mobility information from a dilute colloidal dispersion using electrophoretic light scattering (ELS) is disclosed. Both laser Doppler electrophoresis and phase analysis light scattering data analysis methods may be applied to a scattered light signal simultaneously. Unlike previous ELS apparatuses and methods, the disclosed apparatus and method can measure electrophoretic mobility distributions in high ionic strength media. It can detect the presence of electrochemical phenomena such as electrode polarization and electrolysis, and apply corrections to the measured electrophoretic mobility values thus providing electrophoretic mobility information about samples with greater accuracy, precision, and reliability than prior ELS implementations. Improvements to the optical configuration of the apparatus are also disclosed that increase the robustness of the apparatus. Many of the aspects of the disclosure may be applied to the measurement of electrophoretic mobilities of particles in low polarity media and also particles with low surface charge in polar or non-polar media with greater accuracy, precision, and reliability than prior ELS implementations.
