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.

Supplier: Restek

Cartridges have been specifically designed to provide consistent and reproducible results for the method or application stated.

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

Supplier: Restek

The reversing cartridge design allows convenient inverted elution of strongly retained analytes using minimum solvent volumes. Ideal for extraction of pesticides in water.

Supplier: Thermo Fisher Scientific

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

Supplier: WATERS

Silica-based bonded phase with strong hydrophobicity used to adsorb analytes of even weak hydrophobicity from aqueous solutions.

Supplier: Restek

These cartridges are manufactured using high density polypropylene and have polyethylene frits unless otherwise noted. Hydrophilic (polar) adsorbents used to extract hydrophilic analytes from nonpolar matrices, such as organic solvents (e.g., polar contaminants from sample extracts).

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: Restek

Resprep tubes, frits, caps, and connectors for method development needs.

Supplier: Thermo Fisher Scientific

A polar sorbent for both polar and anion exchange interactions.

Supplier: Thermo Fisher Scientific

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

Supplier: Restek

These cartridges are made of glass fiber disks embedded with C18 or C8 bonded silica. These hydrophobic (nonpolar) silica-based adsorbents are ideal to extract hydrophobic analytes from polar matrices, such as water (e.g., pesticides from water).

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™ 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: Thermo Fisher Scientific

These columns feature a highly retentive alkyl-bonded phase for non polar to moderately polar 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: Restek

CarboPrep® cartridges are manufactured from chromatographic-grade, nonporous, graphitized carbon. Our manufacturing process minimises variability and improves recovery and cleanup procedures.

Supplier: Thermo Fisher Scientific

A short alkyl chains with polar functional groups are ideal for the isolation of polar compounds.

Supplier: WATERS

These Oasis® WAX cartridges contain the WAX sorbent, which is a polymeric reversed phase, weak anion exchange mixed mode sorbent that has been optimised for fast, simple, and highly selective sample preparation of strong acidic compounds.

Supplier: Restek

Pesticide residue cleanup SPE cartridges are convenient with multiple adsorbent beds in a single cartridge. It is used in multiresidue pesticide analysis to remove matrix interferences and also exhibits good cleanup of dietary supplement extracts.

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.

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: VARIAN

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.
