Acoustic and electro-acoustic techniques have significant advantages for characterizing particle size distribution and zeta potential when used in conjunction. As such, an optimum technique based on ultrasound should combine both acoustic and electro-acoustic spectroscopy together in one instrument.  The Acoustic & Electro-acoustic Spectrometer DT-1202 is such an instrument.

Acoustic and electro-acoustic spectrometer. Particle size distribution and zeta potential with minimizing sample volume.

Model DT-100 has a unique Acoustic sensor for characterizing particle size distribution by measuring ultrasound attenuation at set of frequencies from 1 to 100 MHz, as well as sound speed. This method can be referred to as “ultrasound scattering”.

This instrument measures zeta potential of concentrated dispersions and emulsion. Consequently, it is similar to the model DT-300. However, in addition it allows conducting titration due to 2 burettes. Consequently, it provides data on iso-electric point, surfactant optimum doze, sample kinetics changes. This instrument can be supplied with conductivity probe when samples are aqueous solutions. Temperature probe and pH probe are standard options of this model.

DT-330 Universal Zeta Potential probe for Particulates and Porous materials.  This Universal Zeta Potential probe is capable of measuring zeta potential in practically all types of heterogeneous systems, which includes Particulates and Porous materials:

Acoustic Particle size distribution in concentrated dispersions and emulsions. These two particle size analyzers are different models using ultrasound. All measurement principles and software are the same.

This instrument is for process monitoring of particle size online and quality control applications. Therefore, it can continuously measure Particle size distribution and/or Zeta potential.

This longitudinal Acoustic Rheometer instrument characterizes visco-elastic properties of Newtonian and non-Newtonian liquids of any composition while treating them as homogeneous.

This electric conductivity meter measures electric conductivity of non-aqueous solutions, low and non-polar liquids when dielectric constant is very small.

Longitudinal visco-elastic properties, compressibility, includes software items.
