Ionic liquid based solid phase microextraction coupled to chromatography for high efficient determination of organic compounds

Solid phase microextraction (SPME) is one of the most popular sample preparation methods which can be applied to organic compounds allowing the simultaneous extraction and preconcentration of analytes from the sample matrix. It is based on the partitioning of the analyte between the extracting phase, generally immobilized on a fiber substrate, and the matrix (water, air, etc.), and has numerous advantages such as rapidity, simplicity, low cost, ease of use and automation, and absence of toxic solvents. Also ionic liquids as green solvents can be used for modification of fibers and improving its characteristics. In this paper we investigated on preconcentration and determination of organic compounds with ionic liquid based solid phase microextraction coupled to chromatography
