Brookhaven ZetaPlus
- Current Status: Up
The Brookhaven ZetaPlus measures the velocity of charged, colloidal particles in solution. Laser light passes through the sample/suspension and is compared with the frequency of a reference beam. The shift in the frequency, called a Doppler Shift, and the magnitude of the shift correspond to the polarity and the magnitude, respectively, of the electrophoretic mobility. The zeta potential is calculated from the solution conditions and the measured mobility. Because it is based on a light scattering technique, this instrument can only be used to analyze suspensions with a very low concentration of particles (< 0.1%). It is also used to measure the size and size distribution of sub-micron particles.
