Taurine is a biologically significant molecule with a zwitterionic character, which makes it a difficult analysis target. COSMOSIL HILIC has a unique anion-exchange mechanism which allows strong retention of taurine with good peak shape. It is USP packing type L104, specified on the official monogram for taurine. >> Gen...

Due to the lack of retention on ODS columns, oligosaccharides have typically been analyzed on specialty sugar columns. We have successfully analyzed inulins using COSMOSIL Sugar-D, a specialty column for saccharide analysis, and PBr, a unique reversed-phase column for polar and non-polar analytes. About Inulin Inulin stru...
