electroacoustic and conductivity pore analyzers

Wave 3805 image The technique of electroacoustics is now available for the rapid determination of mean pore size in a variety of sample types without mercury, without vacuum pumps, without pressurized gases, and without the wait. The same seisomolectric effect is also employed to reveal the zeta potential of the surface inside the pore structure. The measurements of percent porosity uses very high frequency conductivity measurements.
Patents pending.

The WAVE series of pore characterization systems consists of three models.The WAVE 3805 can measure all three pore-related properties from a single control module using two probes. Pore size analysis and three-in-one capability of the 3805 represents the newest, and probably the most unique, in pore characterization systems.

The WAVE 2305 offers measurement of pore zeta potential and porosity.

The WAVE 1905 is dedicated to the rapid dermination of just porosity for those customers who are most interested in that parameter.

MEASUREMENTS
All measurement modes are performed in a similar fashion, that is, the sample is fully wetted with a suitable fluid (water, organic solvent or electrolyte depending on the exact measurement to be done and pore size range of the sample) and then contacted by the appropriate probe (the probes can be used in any orientation to facilitate ease of use). The electronics and measuring circuits do the rest. Results are displayed on screen in a minute or two and saved to the database.

APPLICATIONS
There is no fundamental limitation as to the type of material that can be analyzed using the WAVE analyzers so long as the sample is stable with respect to the fluid used to wet the pores, and for pore size that they are within the range of the technique. Typical applications include green and fired ceramics, core samples, chromatography silicas and resins, tablets, battery components, friction products, frits, cement and other construction materials, to name but a few.

SOFTWARE
The WAVE analyzers are supplied with Windows®-based software for control, data acquisition and report generation, and which runs on the control module so a separate PC is not required. The WAVE software features an easy-to-use interface, prompted calibration procedures, a defined-materials database and real-time data capture. Data are stored in database format and can be output in popular .csv format.
