The sorbent required for the purification of a specific substrat will vary according to the structure of the said substrate. Wether it is ionized or neutral and depending on its polarity and solubility, the appropriated chromatographic stationary phase will vary. In order to better fulfill those different needs, SiliCycle offer a wide variety of sorbents for normal and reversed-phase. Please refer to the sorbent selection guide to select the most appropriated phase.
Chromatography with silver nitrate is a well known and established methodology for the separation of non polar compounds with similar polarities. Generally, with a mixture of unsaturated compounds such as alkenes, lipids, steroids, terpenes, etc, standard separation procedures lack in efficiency. However, by using SiliaBond® Silver Nitrate for your column chromatography along with SiliaPlate™ Ag for your TLC, you will have the necessary tools to circumvent the problem.
SiliaBond® C18 (or C18) is the traditional matrix for reversed-phase chromatography. The high loading provides the highest degree of hydrophobicity commercially available. Considered as the least selective phase since it interacts with a wide range of organic molecules.
SiliaBond® C18 (or C18) is the traditional matrix for reversed-phase chromatography. The high loading provides the highest degree of hydrophobicity commercially available. Considered as the least selective phase since it interacts with a wide range of organic molecules. Also used in ion-pairing chromatography (non-endcapped) for the separation of biomolecules.
The SiliaBond® C18 17% BDS is the most efficient deactivated C18 reversed-phase. This versatile support is the best choice for your applications in reversed-phase chromatography. This chromatographic phase has been compared with different competitors and presents a better separation for basic compounds.
This non-endcapped version of the SiliaBond® C18 17% BDS, presents a perfect monolayer of dimethyloctadecylsilane and silanol functions. The hydrophilic/hydrophobic balance is permitting to use a mobile phase with a higher concentration of water and ion pairing conditions for separation of biomolecules.
SiliaBond® C18 11% is used as a reversed-phase chromatographic matrix when large hydrophobic molecules are too strongly retained on SiliaBond C18 with higher carbon content.
SiliaBond® C8 (or C8) is a reversed-phase matrix with a moderate degree of hydrophobicity that works well for separating a wide range of compounds. It can be used instead of C18 when shorter retention times are desired.
SiliaBond® C8 (or C8) is a reversed-phase matrix with a moderate degree of hydrophobicity that works well for separating a wide range of compounds. It can be used instead of C18 when shorter retention times are desired.
SiliaBond® C4 (or C4) provides less retention towards non-polar compounds than C18 and C8, and is useful in ion-pairing chromatography or to separate large biomolecules. It works best for molecules with a large hydrophilic region or in case where the hydrophobic region is buried within the structure.
