LiChrospher® ADS Online Sample Prep Cartridges

The inner surface of the porous particles is exclusively covered with a hydrophobic dispersion phase (C4, C8, C18 alkyl chains). These adsorption centers are freely accessible for low molecular analytes. Owing to the classical reversed-phase chromatographic properties of LiChrospher® RP ADS, these sorbents also can be used for ion-pair chromatography. This means that charged compounds can also be enriched and extracted by adding an appropriate ion-pair reagent (e.g. octanesulfonic acid) to the mobile phase.
