Description
The electrokinetic properties of an aqueous suspension can be measured with an electroacoustic based apparatus such as the Matec ESA-8000 which is manufactured by Matec Instruments. This instrument excites an aqueous suspension of particles with a high frequency electric field. The interaction between the charged particles and the alternating electric field causes the particles to oscillate in the water thereby producing a sound wave whose amplitude is measured by the instrument. The amplitude of the sound wave, also called the Electrokinetic Sonic Amplitude (ESA) is directly proportional to the zeta potential of the particles in the suspension. Thus, the ESA is zero when the zeta potential is zero. The IEP of the suspension can then be determined by measuring changes in the ESA with varying pH because the IEP is the pH at which the ESA (and zeta potential) is zero.
Matec ESA-8000A is a phase sensitive detector which has a computer controlled data acquisition system directly yielding attenuation changes.
