Research Abstract	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.
