| Discovery Ag-Ion (silver-ion) SPE |
When silver ions are loaded and immobilized on to an SCX phase as counter-ions, they have the ability to form polar complexes with unsaturated fatty acid double bonds under normal-phase conditions. Discovery Ag-Ion SPE was developed for the fractionation cis/trans isomers, and can also resolve FAMEs by degree of unsaturation in which retention strength increases with increasing number of double bonds. As a result, Discovery Ag-Ion SPE allows users to fractionate FAME samples prior to GC analysis thereby simplifying analytical chromatography and improving method accuracy.
Discovery Ag-Ion SPE phases are loaded with silver using a proprietary procedure to offer optimal resolution, performance, and capacity. Each lot is tested and quality controlled for cis/trans FAME resolution.
