Silicapak E-411
Silica 5SIL |
Packed with silica gel with no chemical modification. Suitable
for normal phase analysis using non-polar organic solvent. |
| Silica 5C8 |
Used when retention time is too long with C18 or when it is
too short with 5C4 and 5TMS. Suitable for ion-pair chromatography because
mass transfer is fast and equilibrium is reached quickly. |
Silica 5C4
Silica 5TMS
Silica 5CN |
Used when the retention time is too long with C18 and C8.
Polarity of the packing material increases in the following order: 5C4 >
5TMS > 5CN. |
| Silica 5NH |
Suitable for normal phase analysis of saccharides using a
mixture of water and organic solvent as eluent. |
Silica 5NPE
Silica 5PYE |
These columns can distinguish differences in stereochemistry.
Suitable for the separation of stereoisomers. |
*Pore size of all silica-based columns described in this page is approximately
100 angstrom.
