| 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) |
