Solid phase extraction cartridges, Bond Elut™ PBA

Supplier: VARIAN
Description: PBA is a unique sorbent consisting of a phenylboronic acid covalently linked to a silica gel surface. Covalent processes result in a higher retention to the sorbent surface than other mechanisms, resulting in superior clean-up. The boronate group has a high specificity for cis-diol containing compounds such as catechols, nucleic acids, low molecular weight proteins and carbohydrates.

Solid phase extraction cartridges, Bond Elut™ C2

Supplier: VARIAN
Description: 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.

Solid phase extraction cartridges, Oasis® HLB

Supplier: WATERS
Description: Oasis® HLB cartridges contain the Oasis® HLB sorbent, which is a universal polymeric reversed phase sorbent that was developed for the extraction of a wide range of acidic, basic, and neutral compounds from various matrices using a simple, generic protocol.

Solid phase extraction cartridges, Bond Elut™ SI

Supplier: VARIAN
Description: 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.

Solid phase extraction cartridges, Bond Elut™ AccuCAT

Supplier: VARIAN
Description: 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.

Solid phase extraction cartridges, Bond Elut™ PSA

Supplier: VARIAN
Description: 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.

Solid phase extraction cartridges, Bond Elut™ PCB

Catalog Number: (VARI12105032)
Supplier: VARIAN
Description: Bond Elut™ PCB is a specially designed sorbent which allows for the facile extraction of polychlorinated biphenyl (PCB) compounds from a variety of matrices. Desired analytes can be loaded and eluted using a simple, single solvent method prior to analysis by GC/ECD.

Solid phase extraction cartridges, Bond Elut™ Alumina

Supplier: VARIAN
Description: Alumina, like silica, is an extremely polar sorbent. The alumina surface tends to be slightly more stable under high pH conditions than unfunctionalised silica. The small particle size of the Bond Elut™ Alumina range ensures high extraction efficiency even when small bed masses are used.

Solid phase extraction cartridges, Bond Elut™ Plexa PCX

Supplier: VARIAN
Description: Bond Elut™ Plexa PCX uses a polymeric cation exchange resin that combines the outstanding properties of Bond Elut™ Plexa - superior flow characteristics and improved analytical performance - with strong cation exchange functionalities. This mixed-mode SPE sorbent removes neutral and acidic interferences from the matrix, concentrates basic analytes and therefore improves sensitivity in the determination of basic compounds.

Solid phase extraction cartridges, Bond Elut™ Focus

Supplier: VARIAN
Description: 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.

Solid phase extraction cartridges, Bond Elut™ PRS

Supplier: VARIAN
Description: Bond Elut™ PRS is a strong cation exchange sorbent that is also relatively high in polarity. With no appreciable degree of hydrophobicity, in non-polar solvents, PRS is capable of polar and hydrogen bonding interactions. Due to the very low pKa of PRS, a high ionic strength eluent must be used, and so the use of PRS is recommended for weaker cationic species such as pyridinium compounds.

Solid phase extraction cartridges, Bond Elut™ NEXUS and NEXUS WCX

Supplier: VARIAN
Description: Bond Elut™ NEXUS is an ultra-clean polymeric sorbent which has bi-modal porosity and a high surface area. NEXUS offers a nonpolar retention mechanism with no pre-conditioning required. The large particle size makes NEXUS ideal for extractions from highly viscous samples, such as horse urine.

Based on the same base polymer technology, Bond Elut™ NEXUS WCX is a weak cation exchange sorbent that offers extra selectivity for analytes, such as quaternary ammonium drugs and anabolic steroids.
