Electrophoresis light-scattering method

The electrophoresis light-scattering method (Model ELS-800, Ostuka Electronics Co. Ltd., Japan). [Pg.395]

One way to increase the range of measurement may be in the use of light scattering (Doppler electrophoresis) to determine particle velocities. Such methods are used in contemporary commercially available analytical particle electrophoresis apparatuses. However, presently available equipment is not designed for ready exchange (replacement) of chamber surfaces for electro-osmosis studies. [Pg.126]

Phase analysis light scattering (PALS) is a technique that is very similar to laser Doppler electrophoresis (LDE) and is used to measure the electrophoretic mobilities of colloidal particles. This technique is particularly suited to measurements of charged particles suspended in nonpolar media and sensitivity of the method is far superior to that which could be obtained by LDE measurements. It makes use of a cross-beam technique and offsets one of the laser beams relative to the other by several kEIz. ... [Pg.661]
