Abstract
A method including: sonicating a liquid suspension of first particles; and analyzing the liquid phase for second particles. An apparatus including: a sonicator adapted to sonicate a liquid suspension of first particles; and a first analyzer adapted to analyze the sonicated liquid phase for second particles. The method and apparatus can be used to analyze the adhesion force relationships between the main or host first particles and guest or surface additive second particles.
Claims23
An apparatus comprising:
- a sonicator adapted to sonicate a liquid suspension of first particles;
- a first analyzer adapted to analyze the sonicated liquid phase for second particles;
- and
- further comprising a data analysis station is adapted to correlate the energy expended by the sonicator with the yield of second particles in the sonicated liquid phase to determine the adhesive force between the first particles and the second particles prior to sonication.
An apparatus comprising:
- a sample preparation station adapted to generate particle dispersions;
- an ultrasonication station comprised of a plurality of ultrasonic horns adapted to sonicate a liquid dispersion of first particles;
- a sample separation station adapted to separate first particles from a liquid medium in the resulting sonicated dispersion;
- a sample analysis station adapted to analyze the resulting separated liquid medium for second particles;
- a data analysis station adapted to analyze the resulting second particles data from the sample analysis station;
- and
- a programmable robot adapted to continuously advance a sample container from the sample preparation station, to the ultrasonication station, to the sample separation station, to the sample analysis station, to the data analysis station, and to a sample retention or discard station.
An apparatus comprising:
- a sonicator adapted to sonicate at least one liquid suspension of first particles with pulsed ultrasonic energy, and
- wherein the sonicator has a power source adapted to convert electrical energy to mechanical energy and thereafter divide and deliver the mechanical energy in equal amounts to two or more horn members.
An apparatus comprising:
- an ultrasonic station comprising a plurality of ultrasonic horns adopted to sonicate a liquid dispersion of first particles;
- a sample separation station adapted to separate first particles from a liquid medium in the resulting sonicated dispersion;
- and
- a sample analysis station to analyze the resulting separated liquid medium for second particles.
