Wakopak® Wakosil® C18 Series
Wakopak® Wakosil® series is a column packed with a completely spherical, porous, silica gel-based packing agent for HPLC. Wakopak® Wakosil® series assortment focuses on columns of different separation modes, especially reverse-phase distribution ODS packing agents, Wakopak® Wakosil® C18 series.
Features
High-endcapping type
ODS bond and endcapping treatments are performed FUJIFILM Wako’s unique surface treatment technology. Excellent peak shape and reproducibility are obtained for various samples, ranging from acidic to basic.
- Wakopak® Wakosil® C18 type (5C18, 7C18, 10C18)
It is a high-retention capability/high-resolution type with a carbon content of 20%, which is particularly effective for samples of high polarity and weak retention. - Wakopak® Wakosil® 5C18 AR
It is a polymeric ODS packing agent that minimizes ODS leakage and shows excellent durability, even under acidic mobile phases and water-rich conditions. - Wakopak® Wakosil® C18-200 type (5C18-200, 10C18-200)
The carbon content is as low as 12%, and rapid analysis can be performed. However, the resolution is almost equivalent to that of the Wakopak® Wakosil® C18 type, and high resolution is maintained.
Endcapping type
- Wakopak® Wakosil® 5C18T, 5C18-200T
Endcapping is performed after ODS bond, but a small amount of silanol group remains. It is useful when using reverse-phase distribution and slight silanol adsorption for separation, such as with glycosides and medical products. For neutral samples, this product exhibits retention characteristics similar to those of the high-endcapping type.
Non-endcapping type
- Wakopak® Wakosil® 5C18N, 5C18-200N
The silica gel surface is maximally ODS-bonded, but endcapping is not performed. It is a packing agent with more silanol group adsorptive property than the Wakopak® Wakosil®-T type.
In addition, the residual silanol content of Wakopak® Wakosil® 5C18N is higher than that of 5C18-200N due to the physical properties of silica gel, resulting in higher adsorptive effects.
It is useful for separation analysis of positional isomers or compounds with similar structures.
