Description
Based on Acoustic Attenuation Spectroscopy, the patented Acoustic Particle Sizer (APS) measures particle size distributions without the need for sample dilution in the particle size range 5 nm to 100+ microns. Versatile rugged instrument can analyze samples such as the following: aqueous/non-aqueous, opaque, highly viscous, corrosive, emulsions, neutrally buoyant, sterically stabilized, low Zeta potential, etc. Simultaneous measurement of percent solids, longitudinal viscosity, pH, conductivity, temperature, and sound speed and attenuation spectra. Automated titration capability allows measurement of reagent effects on particle size.
The APS produces undiluted PSD data simultaneously with Longitudinal Viscosity, Percent Solids, pH, Conductivity, Temperature, and acoustic attenuation and sound speed spectra. Call on the particle size and Zeta potential analysis leader for the last thirty years, Matec Applied Sciences. Our knowledgeable staff will gladly perform free sample analyses for evaluation; or if you prefer, we will visit you for an on-site demonstration. HOW IT WORKS The APS produces PSD data from acoustic attenuation spectroscopy measurements without the need for sample dilution (up to 60% vol). The APS also measures Longitudinal Viscosity, Percent Solids, pH, conductivity, and temperature of samples in the particle size range of 5 nm to 100 microns. As sound travels through a slurry or colloid, it is attenuated. The level of attenuation is related to the particle size distribution. The APS measures acoustic attenuation very accurately over the 1-100 MHz frequency range. Because sound travels through all material media, APS acoustic attenuation measurements can be made on high-concentration and/or opaque samples. Particle settling is not a problem since samples can be stirred or pumped during the measurement
The Acoustic Particle Sizer-200di (APS-200di) supports the use of disposable measuring cups for analysis, which is convenient for cleaning.
