Silica-based Columns (Others)

E-411 · Silica gel packed column without any chemical modification
5SIL · Uses high-purity silica (99.99%)
· Like E-411, suitable for normal phase analysis using a nonpolar organic solvent
5C8 · To use when the retention capacity of C18 is excessively higher or that of 5C4 is excessively lower
· Applicable to ion-pair chromatography because of its rapid mass tranfer and achivement of equilibrium
5C4 · To use when the retention capacity of C18 or C8 is excessively high
5CN · Utilizes reversed phase interaction and pie-electron interaction to separate regioisomers, which typically cannot be separated with ODS, C8, or C4 columns
5NPE
5PYE
· Utilizes several types of interactions based on pie-electons to separate structural isomers
5NH · Suitable for saccharides analysis by hydrophilic interaction chromatography (HILIC)
