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.

Supplier: VARIAN

Bond Elut™ Focus solid phase extraction cartridges with enhanced polar recovery. Features a unique amide functionalised polar-enhanced sorbent technology that delivers outstanding retention for polar and non-polar analytes.

Supplier: VARIAN

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.

Supplier: VARIAN

CP-Sil 5/C₁₈ CB for PCB has a lower polarity than 100% polydimethylsiloxane due to its C₁₈ substitutions. Due to the absence of cyano groups it provides high signal-to-noise ratios for ECD detectors.

Supplier: VARIAN

Bond Elut™ C2 is a fairly non-polar sorbent because of the short chain length of the functional group. C2 is often used during the process of method development if analytes are retained too strongly on a C8 or C18 phase. The polarity of C2 is slightly lower than a cyano phase for polar interactions.
