What Does it Cover?

Ionic liquid phase columns offer fascinating properties in GC. They are uniformly very polar, and this confers interesting properties to their retention behaviour. For instance, in many cases, the elution temperature of analytes is much lower on IL phases. Thus we obtain reduced elution temperature for fatty acid methyl esters (FAME) as the polarity of the phase increases from IL59, IL60, IL76, IL82, IL100 to IL111. This could be of interest in reducing the upper temperature of analytes. We often combined IL columns with other phases in multidimensional gas chromatography (MDGC) analysis – or sometimes might use two IL phases in our MDGC studies. As an example, we investigated a MDGC approach where we combine a non-polar phase column which essentially separates FAME on the basis of homologue number, with a polar IL phase which separates based on the increasing polarity of the unsaturated bonds. In other work, comprehensive two-dimensional gas chromatography (GC×GC) with IL phases offers exceptional polarity differences, and combinations of IL and regular phases must be carefully selected in order to provide best use of the 2D GC×GC space. This presentation will cover introduction to IL phases, their unique performance as stationary phases, an overview of MDGC and GC×GC, then selected applications with IL phase columns.
