Abstract Content
An increasing demand on analytical laboratories world-wide seeks to combine sampling and sample preparation methods into a single step. These methods must allow for high throughput analysis of analytes in a variety of matrices while also producing low detection limits, high selectivity, and high enrichment factors. Ionic liquids (ILs) are an attractive class of non-molecular solvents whose versatility allows them to be incorporated into various microextraction methods. ILs have negligible vapor pressures at room temperature, possess a wide range of viscosities, can be custom-synthesized to be miscible or immiscible with water and organic solvents, often have high thermal stability, and are capable of undergoing multiple solvation interactions with many types of molecules. ILs can be structurally tuned to modulate desired physio-chemical properties while retaining their unique solvation capabilities. In this talk, the synthesis of new classes of ILs and polymeric ionic liquids (PILs) will be highlighted. The incorporation of these materials in solid phase microextraction (SPME), single drop microextraction (SDME), and dispersive liquid-liquid microextraction (DLLME) methods for the extraction of a wide class of analytes from environmental (polycyclic aromatic hydrocarbons, borate/boric acid, emerging contaminants), foods (coffee), pharmaceutical (genotoxic impurities), and biological (nucleic acids) samples will be discussed.
