Popis: CBA is a mid-polarity sorbent and weak cation exchanger (pKa 4,8). It can be used with a wider range of counter-ions than lower pKa sorbents like SCX and will demonstrate easier elution of quaternary amine functionalised analytes.

Popis: Bond Elut™ PSA is an alkylated amine sorbent that contains two different amino functionalities, one secondary and one primary. This gives a slightly higher pKa and ionic capacity compared to Bond Elut™ NH₂. The PSA functional group is a very effective bidentate ligand and is therefore an excellent sorbent for chelation applications. PSA has a significantly higher carbon load than most amino functional sorbents and thus is a better choice for polar compounds, which retain too strongly on Bond Elut™ NH₂.

Popis: Hi-Plex HPLC columns deliver improved efficiency, lower operating pressures and longer column lifetimes from monodispersed materials. With a range of ligand counter ions for optimum selectivity and resolution and materials matched to the USP definitions of media types L17, L19, L34 and L58, the Hi-Plex range is ideal for isocratic separations using water or dilute acid as the eluent. This simplifies your HPLC system requirements and eliminates the use of potentially hazardous organic solvents.
