Abstruct: In this chapter, how the electrophoresis works in polyoxometalate chemistry was summarized in detail. Since POM clusters are too small for showing traditional molecular sieving effect required for separation by electrophoresis, they show differences in electrophoretic mobility. The mobility is well understood by a correlation between the cluster mobility and structurally determined surface charge density. By observing these mobility differences in mixed POM solutions, each component can be separated. The electrophoretic chromatography for POMs is now discussed for a genuine analytical technique for investigation of cluster species in solution.
