Acoustic & ElectroAcoustic Spectrometer (DT-1200)
Acoustic & ElectroAcoustic Spectrometer characterizes both particle size and zeta potential of concentrated suspensions. The instrument contains both acoustic and electroacoustic sensors. As a result, it is capable of measuring attenuation spectra (for particle size measurement) as well as colloid vibration current (for zeta potential measurement) simultaneously. This instrument allows us to measure particle sizes and zeta potential in highly concentrated slurries and does not require the slurry to be conductive or transparent. Therefore it can be applied to dark and nonaqueous systems such as water in diluted bitumen emulsion systems, i.e., studying water drop sizes and emulsion stabilization mechanisms.
