The size range suitable for measurement is between 1 nm and 100 pm. 3.3.3 Delsa™ Nano Series from Beckman Coulter Inc., USA [19] In these instruments the principle of electrophoretic light scattering (ELS) through FST is used to measure the zeta potential of concentrated samples (0.001% ...
The use of Phase Analysis (instead of the standard amplitude analysis) allows for the more accurate and precise measurement of small Doppler shifts. This means that zeta potential measurements can be made in high ionic strength or high dielectric environments (like alcohols and organic solvents). ...

the basic principle of the ELS method, the optical path design of the instrument, the hardware system and the design of the software system are introduced. The accuracy and stability of the Zeta potential analyzer are verified by the design experiment and the experimental results show that the ...
The Nicomp 380/ZLS uses the method of Electrophoretic Light Scattering (ELS) to measure Zeta potential. To make a measurement, a small aliquot of sample is typically placed in a disposable plastic cuvette. Then the palladium electrodes are inserted. The entire cell is placed into the Nicomp 380...
