This review encapsulates the work which appeared in the literature during 1995–2015 on the use of microemulsion as the mobile phase in the analysis of inorganic anions and organic compounds by thin-layer chromatography (TLC). Among anionic, cationic, and non-ionic surfactants used as one of the components of oil-in-water (O/W) and water-in-oil (W/O) microemulsions, sodium dodecyl sulfate (SDS) (anionic surfactant) has been found the most effective for the analysis and separation of different compounds. Compared to the work performed with the use of W/O microemulsion, little work has been reported on use of O/W microemulsion in the TLC—high-performance thin-layer chromatography (HPTLC) analysis of organic compounds. In contrary to TLC, more work has been done on use of O/W microemulsion in high-performance liquid chromatography (HPLC). Out of the sorbent phases, silica gel in combination with microemulsion eluent has been favorable for realizing analytically useful separations. Classification of microemulsions and surfactants is also discussed in the present review.
