La famille de produits PLRP-S se compose de plusieurs tailles de pores et de particules ayant tous la même structure chimique et les mêmes caractéristiques d'adsorption fondamentales. Les particules sont intrinsèquement hydrophobes, si bien qu'aucun ligand alkyle de phase greffée n'est nécessaire pour des séparations en phase inverse. Cela donne un matériau hautement reproductible exempt de silanols acides et d'ions de métaux lourds. La large gamme de produits disponibles propose des colonnes adaptées aux séparations analytiques et aux purifications préparatives.

Bond Elut™ SAX is a strong anion exchange sorbent ideally suited for the extraction of compounds such as carboxylic acids, which may not retain effectively on weak anion exchange sorbents. The sorbent is supplied in the chloride counter ion form. You can modify the selectivity of the phase by replacing the chloride ion with other anions, such as acetate and hydroxide.

Supplier: VARIAN

Bond Elut™ NH₂ is a weaker anion exchanger than sorbents such as SAX (a quaternary amine sorbent that is always charged) and is therefore a better choice for retention of very strong anions, such as sulfonic acids, which may retain irreversibly on a SAX sorbent. Similar to Diol and SI sorbents, Bond Elut™ NH₂ is excellent for the separation of structural isomers.

Supplier: VARIAN

Native silica is generally regarded as the most polar SPE sorbent available. Bond Elut™ SI is particularly effective at separating compounds with a very similar structure. Applying the analytes in a non-polar solvent, then increasing the solvent polarity by increasing the concentration of a polar modifier, such as THF or ethyl acetate, delivers effective separations.
