Operating Procedure Available Options

The user fills the sample chamber with 0.1 – 150 ml of sample, defines the sample in a simple dialog box, selects the desired experiment protocol, and clicks on “RUN”.

When the measurement is complete, the user empties the sample, and then rinses the system with water or suitable cleaning solution.

For Zeta potential measurements sample volume can be as little as 0.1 ml. For Particle Sizing measurements, sample volume can be as little as 3 mL for model DT-110, or DT-1210 with disposable cell.

Automatic Titration with 1 or 2 burettes;

pH / Temperature measurement;

Conductivity measurement, aqueous and non-aqueous;

Circulating pump for very viscous samples;

Ports for remote “on-line” measurements;

Rheology longitudinal;

Temperature heating control;

Disposable sample cell with sample volume <5 mL.

(1) Instrument can measure attenuation spectra well beyond 60 vol %, but theory for computing PSD from this data is limited to 60 vol %. The isoelectric pH is accurate over the entire range, however, some decrease in the absolute value of zeta potential may be experienced as one approaches the volume fraction limits. (3) In calculating the particle size the important viscosity is that experienced by the particle as it moves in response to the sound wave. This “microviscosity” in cases such as gels or other structured systems may be significantly less than the viscosity of the media measured with conventional rheometers which measure viscosity over a scale much larger than the particle.
(2) For titration experiments it may be necessary to use external circulation pump to provide adequate mixing of reagents for quite viscous samples. (4) Particle size range for zeta potential measurement might depend on the density contrast.
