一般描述
应用：世界上第一个商业色谱柱，在我们的气相色谱柱极性等级范围中级别超过100。与非极性和中间极性相相比，它的选择性最高，因此具有非常独特的洗脱模式。这种极性极高的色谱柱可承受的最高温度达到270ºC，令人印象深刻。该色谱柱是从中性分析物中分离可极化分析物（包含C-C双和/或三键）的绝佳选择。它也是良好的GCxGC色谱柱选择。2010年推出。

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.
