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) |
