Title: Exploiting Ionic Liquids and Polymeric Ionic Liquids in Multidimensional Gas Chromatography and Sample Preparation
Speaker: Jared L. Anderson
Affiliation: Department of Chemistry, Iowa State University, USA
Abstract:
Ionic liquids (ILs) can be designed to exhibit unique properties for their use in a number of applications in analytical and bioanalytical chemistry. This talk will focus on the design and synthesis of ILs, magnetic ionic liquids (MILs) and polymeric ionic liquids (PILs) and the use of these materials in a number of applications within sample preparation and multidimensional gas chromatography. A series of monocationic and dicationic ionic liquid (IL)-based stationary phases were evaluated as secondary columns in comprehensive two-dimensional gas chromatography (GC×GC) for the separation of aliphatic hydrocarbons from kerosene. In order to further understand the role that structural features of ILs play on the selectivity of nonpolar analytes, a series of dicationic IL-based stationary phases were evaluated using GC×GC. PIL-based sorbent coatings in solid-phase microextraction (SPME) will be discussed in their use for the extraction of a number of analytes within a variety of matrices. Finally, the ability to perform rapid DNA extraction from biological samples using custom-designed MILs will be presented. MIL solvents exhibit a number of advantages that allow them to be used in downstream DNA analysis including polymerase chain reaction (PCR).
