    Scientific instrumentation solutions for CMP slurries, content of large particles sector

    There are two papers published on subject of applicability of ultrasound for characterizing CMP slurries, see below. There are also 2 newsletters, # 1 and # 13 on the same subject. Acoustics provides accurate particle size that agrees well with independent data. It can monitor presence of 1% large particles on the background of small nano-particles. Electroacoustics yields very precise value of zeta potential. These measurements can be done with no dilution, which opens possibility for continuous on-line...

    Scientific instrumentation solutions for zeta potential in porous bodies sector

    Propagation of ultrasound through a porous body creates motion of liquid inside of the pores relative to the solid matrix. This, in turn, causes relative motion of ions that are located in the diffuse layer and on the pores surfaces. This shows us as an electric current. This current is similar to the Streaming Current, with the difference that it oscillates in time. It is called Streaming Vibration Current. There have been 3 papers already published reporting experimental observation of this effect. The first...

    Scientific instrumentation solutions for emulsions and microemulsions sector

    Acoustics makes possible measurement of Particle size of the emulsion and microemulsion droplets with no dilution, which is critical for these systems. Papers presented below indicate very good agreement between this method and independent data. Combination of Acoustics and Electroacoustics could reveal peculiar mechanisms controlling emulsion stability, such as ion exchange in water-in-oil emulsion.

  • Particle Size Measurement - Monitoring and Testing - Laboratory Equipment

    Particle Size Measurement

    Particle size is a geometric characteristic that is usually assigned to material objects with sizes ranging from nanometers to millimeters. There is a wide variety of real systems that contain particles within this size range. These systems are generally polydisperse, meaning that the particles in a particular sample vary in size. Therefore, in order to adequately characterize such systems, it is not sufficient to simply determine a single particle size. We must instead determine the system’s particle size...
