Dispersion Technology Inc., was established in 1996 for developing
analytical instrumentation suitable for characterizing
concentrated complex liquid systems, such as slurries, pharmaceuticals, cement, ceramics, paints, emulsions, and
many more. Since that time we have designed and are
currently marketing worldwide a family of such instruments that
are based on ultrasound, (see
products page for these models). Ultrasound turned out to become a
very versatile tool yielding information not only on particle size
and zeta potential, but variety of
parameters characterizing these complex systems, such as
compressibility, longitudinal viscosity, micro-viscosity,
surface conductivity, electric charges of macromolecules,
etc. These methods can be applied for characterizing zeta
potential not only in liquid particulates but in porous
bodies as well.
We also use conductivity measurements, aqueous and
non-aqueous, for peculiar purposes. Our non-aqueous
conductivity probe can be used for monitoring ionic
composition and surfactant content in low and non-polar
liquids. Our high frequency aqueous conductivity probe
yields information for calculating porosity of porous
materials or volume fraction of solids in dispersions.
We have 5 issued and 2 pending USA
Patents. Our customers
have published over 50 papers in leading scientific
There are numerous
presenting some results collected during 15 years in our
lab. All of our
achievements in this field have been summarized in two
Edition of the scientific book published by Elsevier in 2010
(see a photo on left hand side).
When comparing our instrument with competing technologies /
instruments claiming the same functionality, PLEASE be aware
of necessity of having verification tests. Equilibrium
dilution test is the most appropriate for characterizing
concentrated systems. The tested instrument should provide
the same value of the particle size and zeta potential for
various volume fraction of the same concentrated system, IF
dilution performed with the equilibrium supernate. Failure
to provide such tests from the highest to the lowest limit
of the claimed concentration range, means that such
instrument is not validated.
PLEASE, be aware of the importance of PRECISION and ACCURACY
data for any instrument. Such information should be provided
as validation of proper performance of said instrument.
far as we know we are the
only one company
that has performed and published results of such tests for
sizing and zeta potential within the range 1 – 50 % vl, as
of January 3, 2012.
