Descripción

Descripción general

Application: World′s first commercial column to rate over 100 on our GC column polarity scale. Selectivity most orthogonal to non-polar and intermediate polar phases, resulting in very unique elution patterns. Maximum temperature of 270 ºC is very impressive for such an extremely polar column. Great choice for separation of polarizable analytes (contain double and/or triple C-C bonds) from neutral analytes. Also a good GCxGC column choice. Launched in 2010.
USP Code: None
Phase:

• Non-bonded
• 1,5-Di(2,3-dimethylimidazolium)pentane bis(trifluoromethylsulfonyl)imide

Temp. Limits:

• 50 °C to 270 °C (isothermal or programmed)

Fast GC Analysis of Fatty Acid Methyl Esters Using a Highly Polar Ionic Liquid Column and its Application for the Determination of Trans Fatty Acid Contents in Edible Oils
This study presents a rapid method for analyzing trans fatty acid contents in edible oils using a fast gas chromatography (GC) technique combined with a highly polar ionic liquid column. The method significantly reduces analysis time to under 30 minutes, compared to over 90 minutes required by traditional methods from the American Oil Chemists’ Society (AOCS) and Japanese Oil Chemists’ Society (JOCS). The effectiveness of the fast GC method was confirmed through comparisons of trans fatty acid content in various oils, showing good agreement with results from the official methods. The study highlights the advantages of using m-TFPTAH for methyl esterification, which streamlines the process and enhances throughput.
