Ionic liquids (ILs) are a class of organic molten salt with melting point below 100 °C. They are usually composed of asymmetrical organic cations and anions. Their properties can be readily tuned by changing the composition of cation or anion, so they are also called “designer solvents”. Due to their unique physi-cochemical properties, they were widely used in organic chemistry and analytic chemistry. In this paper, the recent research and application of ILs in the field of extraction pretreatment, chromatography, capillary electrophoresis, electroanalysis and spectrophotometry were reviewed from the type, structure and properties of ILs. The advantages and disadvantages of different ionic liquids in various fields were compared from the perspective of applications mechanism, which can be instructive for the application and development of ionic liquids in future. The prospects of ionic liquids were also discussed and forecasted. The results suggested that ionic liquids showed more potential in the fields of chromatography and capillary electrophoresis. Moreover, designing and developing new types of ionic liquids and exploring the mechanism of the extraction and separation will promote the development of ionic liquids in the field of analytic sciences. Ionic liquids will be widely used in complex sample analysis and trace detection in the near future.
