"Solid Phase Extraction"

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: WATERS

These cartridges contain the Oasis® WCX sorbent, which is a polymeric reversed phase, weak ion exchange mixed mode sorbent that has been optimized for fast, simple, and highly selective sample preparation of strong basic compounds and quaternary amines.

Supplier: WATERS

These cartridges deliver the option of minimum sample preparation. Consists of moulded, high purity PP syringe-barrel bodies with two PE frits to contain the packing material.

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

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

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: 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

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: Thermo Fisher Scientific

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

Supplier: VARIAN

Bond Elut™ SAX is a strong anion exchange sorbent ideally suited for the extraction of compounds such as carboxylic acids, which may not retain effectively on weak anion exchange sorbents. The sorbent is supplied in the chloride counter ion form. You can modify the selectivity of the phase by replacing the chloride ion with other anions, such as acetate and hydroxide.

Supplier: VARIAN

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.

Supplier: WATERS

These cartridges can used with liquid and gas samples and have the unique capability of reverse flow direction, a useful feature for trace enrichment application.

Supplier: VARIAN

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

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.

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.

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.
