Bond Elut AccuCAT cartridges are mixed bed SPE cartridges consisting of a strong cation exchange (SCX) and a strong anion exchange (SAX) sorbent packed into one bed. AccuCAT is effective for the extraction of acidic, basic and neutral analytes from urine and other biological samples. AccuCAT is particularly effective for catecholamine extraction from bio fluids.

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.

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.

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.

Microsorb™ Cyano, a cyanopropylsilane-covered silica, is unique in that it spans both the normal and reversed phase separation modes. When used with aqueous organic mobile phases, compounds elute in an order typical of reversed phase, with polar compounds eluting quickly and hydrophobic compounds being more retained.
