Hello Tlimg,
In response to you clarification, here are more lab services that
measure zeta potential.
==============================================
Beckman Coulter - Particle Characterization Lab Services
Beckman Coulter's Science & Technology Laboratory (part of the
Particle Characterization group) has a number of Beckman Coulter
instruments available for characterization of particulate materials.
Standard ASTM procedures as well as procedures developed by Beckman
Coulter for the investigation of powders, emulsions, colloids and
biological samples can be performed by the laboratory staff of
scientists. The Particle Characterization Lab is available for
applications development and laboratory services.
The trained professionals at the Particle Characterization lab have a
vast amount of experience on a wide variety of materials. The Beckman
Coulter Particle Characterization lab, as well as the entire
organization is committed to working with customers to resolve all of
their particle analysis needs.
For more information on any specific type of analysis, or if you are
not sure what type of characterization is correct for your
application, look at the listed services that are offered, or just
contact the Particle Characterization lab at E-mail:
particle.lab@coulter.com
Services:
-Particle Size
-Zeta Potential
-Surface Area, Pore Size Distributions

Zeta Potential and Electrophoretic Mobility Measurements
Two of Beckman Coulter's instruments, the N4 Plus particle size
analyzer, and the COULTERŪ DELSA 440SX zeta potential analyzer, can
be used separately or together to determine the stability of colloidal
suspensions. Applications include pigments, liposomes, proteins, paper
pulp and many others. The N4 Plus "Unimodal Fingerprint" method can
detect the presence of contaminants in the sample, while the DELSA
440SX's zeta potential analysis can determine whether the suspension
is stable or is likely to agglomerate.
COULTERŪ DELSA 440SX
This is the only commercial zeta-potential analyzer that performs a
simultaneously multi-angle measurement. The multi-angle feature
provides information on the relative amplitude of each mobility mode.
The use of four angles simultaneously also assures that peaks are
actually measurements of particle mobility and not noise artifacts.

Zeta potential is a measure of the magnitude of the repulsion or
attraction between particles in a colloid. Its measurement brings
detailed insight into the dispersion mechanism and is the key to
electrostatic dispersion control.
