Supplier: Thermo Fisher Scientific

A polar sorbent for both polar and anion exchange interactions.

Supplier: VARIAN

Bond Elut CN-U is ideally suited for the extraction of polar compounds from a nonpolar matrix, such as hexane or oils. It is suitable for very polar analytes that may be irreversibly retained on SI or Diol (2OH) SPE phases.

Supplier: Thermo Fisher Scientific

A strong cation exchange sorbent for extraction of charged basic compounds.

Supplier: VARIAN

A medium polarity sorbent with many uses, Bond Elut™ CN-E is ideal for applications in which extremely non-polar compounds would be irreversibly retained on high carbon load sorbents such as C₈ and C₁₈. This endcapped version of the cyano sorbent is best utilised when extracting analytes from an aqueous matrix.

Supplier: VARIAN

Bond Elut™ Mycotoxin is a novel sorbent which cleans up food extracts for improved trichothecene and zearalenone analysis. Results are comparable or superior to competing methods, including immunoaffinity columns (IaC) and charcoal/alumina columns. The sorbent is a proprietary silica-based ion exchange material.

Supplier: Thermo Fisher Scientific

HyperSep™ C8 cartridges, less retentive alternative to C18 for polar and nonpolar compounds.

Supplier: VARIAN

Due to the methyl group and subsequent low carbon load, Bond Elut™ C1 is the least retentive of all alkyl group bonded phases for non-polar compounds. However, due to the extensive end capping of this sorbent to mask polar silanol activity, retention and elution of polar and multi-functional analytes can still be achieved. Typical applications include plasma, urine and aqueous samples.

Supplier: Thermo Fisher Scientific

These columns feature a highly retentive alkyl-bonded phase for non polar to moderately polar compounds.

Supplier: Thermo Fisher Scientific

Ideal for the isolation of polar compounds from non polar matrices.

Supplier: Thermo Fisher Scientific

Strong anion exchange sorbent for extraction of weak acids.

Supplier: Thermo Fisher Scientific

The QuEChERS Extraction Kit is designed for the efficient extraction of pesticides from food samples, ensuring compliance with the 2025 China Pharmacopeia.

Supplier: VARIAN

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.

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.

Supplier: VARIAN

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.

Supplier: VARIAN

The water-wettable, hydroxylated exterior allows excellent flow, even with biological fluids. A gradient of polarity on the polymer surface shunts small analytes to the more hydrophobic centre of the polymer bead, where they are retained prior to the washing and elution steps. Plexa provides these performance enhancements due to a unique polymeric architecture with a non-retentive, hydroxylated, amide-free surface and a non-polar PS/DVB core for retaining small molecules.

Supplier: VARIAN

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™ 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

Bond Elut empty SPE cartridges are made with high purity polypropylene for cleaner extracts.

Florisil is a magnesia-loaded silica gel, extremely polar in nature and ideal for the isolation of polar compounds from non-polar matrices.

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.
