Particle Size & Zeta Potential Analyzer
prob (%)
The NanoPlus is a unique instrument that utilizes photon correlation spectroscopy and electrophoretic light
scattering techniques to determine particle size, zeta potential, and molecular weight. The instrument is
compact and easy to use with an extended analysis range, intuitive software, and multiple sample cells to fit
the user’s application.
The instrument is available in three model configurations:

NanoPlus-1 : Nano Particle Sizing Instrument
NanoPlus-2 : Zeta Potential Instrument
NanoPlus-3 : A Combination Nano Particle Sizing and Zeta Potential Instrument

The NanoPlus is capable of obtaining high resolution zeta
potential analyses even with multi-component samples.
In the example on the right, a mixture of five polystyrene
latexes of different particle sizes were measured. Five
spectrums corresponding to each latex component was
detected. The zeta potential of these components were in
the range of -45 mV to -107 mV.

Evaluation of Dispersion Stability
by Zeta Potential/Particle Size
As the absolute value of zeta potential
increases, colloidal systems give
generally stable dispersions due to
electrostatic repulsion between
particles. However, as the zeta potential
approaches zero, the stability of the
dispersion reduces and aggregation
becomes likely.

 

Principle of Particle Sizing

Particulates dispersed in a solution are normally subject to
Brownian motion. The motion is slower with larger particles and
faster with smaller particles. When laser light illuminates particles
under the influence of Brownian motion, scattered light from the
particles shows fluctuation corresponding to individual particles.
The fluctuation is observed according to the pinhole type photon
detection method so that particle size and particle size
distributions are calculated.

 

Principle of Zeta Potential Measurement
In most cases, colloidal particles possess a
positive or negative electrostatic charge. As
electrical fields are applied to the particle
dispersion, the particles migrate in oppositely
charged directions. As particles are irradiated in
migration, scattering light causes Doppler shift
depending on electrophoretic mobility. NanoPlus
software calculates the amount of Doppler shift
followed by electrophoretic mobility and zeta
potential by combining a heterodyne system and
photon correlation method to perform Fourier
transform (FFT) of obtained correlation function.

 

Concept of FST Method
By conventional methods, scattered light from a concentrated suspension can not be measured
correctly due to multiple scattering (A) or in very concentrated solutions due to its ability to transmit
light. The FST method detects the scattered light from particles through a transparent electrode. The
optical path length is minimized to reduce the effects of multiple scattering. Thus, the NanoPlus can
perform a zeta potential measurement of a concentrated suspension with a high degree of accuracy (B).

through Transparent electrode

 

When the measurement of electrophoresis is actually taken, an electroosmotic current is
generated in the cell due to an electric charge on the cell wall. With a negatively charged cell wall,
the electroosmotic flow phenomenon causes the positively charged ions and particles to gather
together by the cell walls. The solution located by the cell walls migrates toward the negative
electrode during electrophoresis. The solution located in the cell center moves in the opposite
direction (toward the positive electrode) to compensate for the flow by the cell walls. Therefore,
an electroosmotic flow is created during electrophoresis. The NanoPlus is designed to measure
electrophoretic mobility at several points in the cell to obtain a position (i.e. stationary point) not

influenced by electroosmotic flow. As a result, the instrument can calculate and accurately
measure electrophoretic mobility, even if the electroosmotic profile of the system is
asymmetrical due to adsorption or sedimentation of the sample on the cell walls.
