"Solid Phase Extraction"

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.

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.

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 vacuum manifolds allow to simultaneously process up to 12 or up to 24 SPE tubes. Precise flow control is provided through each SPE tube by rotating the independent, screw-type valves in the cover, this ensures the packing will not dry out in some tubes while others finish draining.

Flash cartridges for the purification of organic compounds, and also for scale-up, solid phase extraction.

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™ 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: PHENOMENEX

High recovery of labeled released N-glycans in a microelution format allowing for streamlined processing and clean-up of small sample volumes.

The Bond Elut™ Certify extraction cartridge utilises a packed bed consisting of a special, non-polar C8 sorbent and a strong cation exchanger (SCX). Certify is most commonly used to extract basic (cationic) drugs from urine and blood, but it is also very effective for extraction of a wide range of compounds from a diverse range of aqueous matrices.

Bond Elut™ EWP is based upon standard particle size silica but with 500 Å pores to allow more efficient extraction of large molecules (>15000 MW), which are typically excluded from standard porosity silica phases.

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.

Bond Elut™ ENV, a PS/DVB polymer, is designed for the extraction of polar organic residues. It contains 125 μm spherical particles with a high degree of cross linking, advantageous for high volume, fast flow-through applications.

Supplier: VARIAN

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.

Supplier: VARIAN

Bond Elut™ C18 OH is a non-end capped version of the octadecyl bonded phases that enables the silanols on the silica surface to be more active. This low-load C18 has well-controlled silanol activity that permits the fractionation of metabolites and enhances retention of basic compounds compared to an endcapped C18. The pore size makes it a good choice for peptide extraction.

Supplier: VARIAN

Bond Elut™ PH is a non-polar bonded silica material which exhibits a different selectivity to alkyl or aliphatic functionalised phases such as C8 or cyclohexyl. The electron density present in the aromatic ring affords an enhancement in the retention of conjugated or aromatic ring-containing analytes due to desirable pi-pi interactions.
