Ionic Liquid GC Column Option for the Analysis of Omega 3 and Omega 6 Fatty Acids

Sigma-Aldrich Supelco
19 Oct 2014

In this application note, a new ionic liquid GC column, SLB®-IL60, is evaluated against another existing wax column for its suitability for the analysis of Omega 3 and Omega 6 fatty acids. The SLB-IL60 column has selectivity similar to wax columns, but is different enough to provide a unique elution pattern. It is not based on a PEG phase. Instead, it has various functional groups that allow for an increased number of interaction mechanisms compared to a PEG phase.

SLB-IL60 Ionic Liquid GC column

Sigma-Aldrich Supelco

SLB-IL60 Ionic Liquid Capillary GC ColumnApplication: Modified (deactivated) version of SLB-IL59 provides better inertness. Selectivity more polar than PEG/wax phases, resulting in unique elution patterns. Higher maximum temperature than PEG/wax columns (300 ºC compared to 270-280 ºC). Excellent alternative to existing PEG/wax columns. Also a good GCxGC column choice. Launched in 2012.USP Code: NonePhase: Non-bonded; 1,12-Di(tripropylphosphonium)dodecane bis(trifluoromethylsulfonyl)imideTemp. Limits: 35 °C to 300 °C (isothermal or programmed)

Gas ChromatographyGas chromatography (GC) is an analytical technique used to separate and quantitate mixtures of small and volatile compounds. Gas chromatographs or GC systems include components such as GC columns, detectors, pumps and autosamplers. Choose from packed or capillary GC columns, flame ionization (FID), photoionization (PID) electron capture detectors and selective or non-selective detectors. Find the best gas chromatographs in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.FatsChromatographyChromatography is a powerful technique used to separate and analyze components of mixtures based on their chemical properties. It is widely used in fields like biochemistry, pharmaceuticals, and environmental analysis. By exploiting differences in the interaction of substances with a stationary phase and a mobile phase, chromatography enables precise purification and quantification of compounds. Whether you're working with complex biological samples or industrial chemicals, chromatography is essential for obtaining high-quality results. Browse our peer-reviewed product directory to find the best chromatography systems, compare products, read customer reviews, and get pricing directly from manufacturers.
