The electromagnetophoretic migration behavior of droplets of 2-fluorotoluene dispersed in 1 M KCl solution was observed. The surface conductivity of 2-fluorotouene droplets could be calculated from electromagnetophoretc migration velocity. When surfactants were added to 1 M KCl containing 2-fluorotoluene droplets, the change of surface conductivity was detected by the measurement of electromagnetophoretic migration velocity. As this result, it was demonstrated that molecules adsorbed on the droplet surface could be characterized and determined from electromagnetophoretic migration velocity. Moreover, for droplets of ionic liquids, it was suggested that the migration velocity was affected by not only the surface conductivity, but also the instinct conductivity. As this result, it was expected that the electromagnetophoresis has the possibility of the new technique for molecules adsorbed on and/or contained in droplets in micro-reaction system.

观察了分散在 1 M KCl 溶液中的 2-氟甲苯液滴的电磁泳动行为。 2-氟甲苯液滴的表面电导率可以通过电磁泳动等迁移速度来计算。当表面活性剂添加到含有2-氟甲苯液滴的1 M KCl中时，通过测量电磁泳动迁移速度来检测表面电导率的变化。结果表明，可以通过电磁泳移速度来表征和确定吸附在液滴表面上的分子。此外，对于离子液体液滴，迁移速度不仅受到表面电导率的影响，还受到本能电导率的影响。因此，预计电磁泳具有微反应系统中吸附和/​​或包含在液滴中的分子的新技术的可能性。
