Dispersion Technology Inc., was established in 1996 intentionally for developing analytical  instrumentation suitable for characterizing particle size distribution and zeta potential in concentrated complex liquid systems, such as 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. Ultrasound turned out to become a very versatile tool yielding information 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.  

On this site, you will find not only the apparatus you need for measuring various liquid based materials, but also detailed information on the theory behind the inventions  and specific instrument descriptions and applications developed by us and our customers.

Model DT-1201 uses acoustic spectroscopy for measuring particle size in concentrated dispersions and emulsions. It applies the same sensor for measuring bulk viscosity,  longitudinal viscosity and compressibility in Newtonian and non-Newtonian liquids. This sensor is also a part of the DT-100 and the DT-600. In addition, DT-1201 contain electro-acoustic sensor for zeta potential measurement. This model can be supplied with number of options, such as titration with two burettes, conductivity aqueous and non-aqueous, pH and temperature measurements, etc.

Model DT-300 is a zeta potential analyzer that can be used for characterizing not only liquid particulates, but porous bodies as well, which makes this instrument unique. It is capable of determining zeta potential of particles in liquids by measuring colloid vibration current and zeta potential of porous bodies by measuring non-isochoric streaming current (seismo-electric effect). This method was used even for studying ions sizes in aqueous and non-aqueous systems.

Model DT-700 is a non-aqueous conductivity probe that uses coaxial cylinder chambers to perform measurement for complete conductivity range. There are currently no comparable instruments on the market for this use. Conductivity is useful complementary parameter for characterizing non-aqueous particulates together with electro-acoustic zeta potential probe.
