METHOD FOR MEASURING DIPOLE MOMENT SIZE OF DIPOLAR PARTICLE

摘要

The invention relates to a method for measuring the size of the dipole (dipole moment) having a dipole particles (dipolar particle) by using the electrophoresis phenomenon and the linear electric field. The present invention that by linear electric field to measure the size of the representative value of the dipole representing the non-uniformity of the zeta potential of the particles (zeta potential) or charge distribution, the first, actively using the non-uniform electric field in the electrophoretic to be. Therefore, there is an opportunity to use a non-uniform electric field in the non-linear electric field for electrophoresis, it is by measuring the non-uniformity of the zeta potential or charge distribution in which the fine particles can be an effective design and prediction of the system that is the particles are dispersed . By showing that a non-uniform electric field can be used in electrophoresis, non using a uniform electric field, as well as dipole quadrupole (quadrupole moment) and multi extreme s (multipole moments) that can develop a variety of electrophoretic apparatus, which can be measured the occasion was provided.
