SPE Sorbents Products & Reviews

Bond Elut Diol resembles unbonded silica as it is known for strong hydrogen bonding with analytes. 20H can also be employed in the nonpolar mode because the hydrocarbon spacer on its functional group provides enough nonpolar character for retention of hydrophobic analytes. Bond Elut Diol is a listed SPE device for the DIN 14333-1 method on benzimidazole fungicides.

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 flowthrough applications.

Florisil is a magnesia-loaded silica gel. Like silica, it is extremely polar in nature and ideal for the isolation of polar compounds from nonpolar matrices. The larger particle size of the sorbent enables fast flow for large sample volumes and therefore can be an attractive alternative to silica if the sample matrix is particularly viscous.

Bond Elut LMS polymeric sorbent lets you elute without having to add amine modifiers, buffers, or acids. The elimination of secondary interactions means that elution of analytes can be achieved with pure organic solvents or HPLC mobile phase-compatible solvent mixtures of low ionic strength. These characteristics are crucial to allow compatibility with LC/MS or other delicate analytical techniques.

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

Bond Elut NEXUS is an ultra-clean polymeric sorbent, which has bimodal porosity and a high surface area. NEXUS offers a nonpolar retention mechanism with no preconditioning required. NEXUS WCX is a weak cation-exchange sorbent that offers extra selectivity for analytes such as quaternary ammonium drugs and anabolic steroids.

Bond Elut NH2 is a weaker anion exchanger than sorbents such as SAX (a quaternary amine sorbent that is always charged), and is therefore a better choice for retention of very strong anions, such as sulfonic acids, which may retain irreversibly on a SAX sorbent. Similar to Diol an SI sorbents, Bond Elut NH2 is excellent for the separation of structural isomers.

Bond Elut PBA is a unique silica SPE sorbent containing a phenylboronic acid functionality that can retain analytes through a reversible covalent bond. This very strong covalent retention mechanism enables high specificity and cleanliness. The boronate group has a strong affinity for cis-diol containing compounds, such as catechols, nucleic acids, some proteins, carbohydrates, and PEG compounds. 

Bond Elut PCB is a specially designed sorbent that allows for the facile extraction of polychlorinated biphenyl (PCB) compounds from various matrices. Desired analytes can be loaded and eluted using a simple, single solvent method before analysis by GC/ECD.

Bond Elut PH is a nonpolar bonded silica material, which exhibits a different selectivity to alkyl or aliphatic functionalized 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.

Bond Elut Plexa PAX sets the new performance standard in analyte cleanup and reproducibility for polar and non-polar acidic analytes. Existing polymeric anion-exchange sorbents can exhibit a broad range of ion exchange capacity from batch to batch. This leads to nonreproducible methods and compromised data. 

Bond Elut PPL is a styrene-divinylbenzene (SDVB) polymer that has been modified with a proprietary nonpolar surface. PPL will retain even the most polar classes of analytes, including phenols. The large particle size allows ease of flow for viscous or particulate-rich water samples, while the high surface area and strong hydrophobicity ensure reproducible extractions with high recoveries upon elution.

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.

Bond Elut SCX is a strong cation exchanger with a very low pKa. Although the pKa is similar to Bond Elut PRS, the presence of the benzene ring in the functional group increases the potential for nonpolar interactions. This nonpolar characteristic becomes particularly important when conducting ion exchange from aqueous systems, where selectivity towards compounds exhibiting cationic and nonpolar character is seen.

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.

The same Bondesil sorbent packed into the industry-leading Bond Elut cartridges is available in bulk for large-scale purification or packing custom cartridges. 

EnvirElut sorbents are specially designed for the extraction of a wide range of compounds from aqueous matrices. EnvirElut herbicides, PAHs, and pesticides are available in standard SPE straight barrel cartridges, which can be used on conventional Vac Elut vacuum manifolds.

Ostro™ 96-well plate provides a novel solution for the cleanup of phospholipids in plasma and serum. Requiring minimal to no method development and using a simple protocol, this technology can be quickly implemented in order to optimize your laboratory's workflow. Removes significantly more phospholipids for cleaner extracts Improves reproducibility for more consistent, robust methods Increases throughput with easy-to-…

EVOLUTE ABN is an advanced water-wettable polymer-based sorbent that extracts acidic, basic and neutral analytes from biological fluids and other aqueous matrices.

Advanced Polymeric SPE for Acidic Analytes

Complete Validation for PFAS Analysis in Compliance with ISO 2167

Clean, activated, and ready-for-use, 30 mesh copper granules remove unwanted elemental sulfur from pesticide and PCB extracts. Granules are much easier to use than copper powder or TBA and eliminate the need for toxic mercury.

Select pH Buffer Pouches - UCT has developed a line of premeasured “ready-to-use” phosphate and acetate buffer pouches. These pouches contain the correct quantity of reagent to quickly and accurately prepare buffers at the correct pH and concentration to simplify solid-phase extraction methods.

These sorbents are composed of a silica backbone bonded with hydrocarbon chains. They are used to extract compounds, which exhibit non-polar or neutral characteristics, from complex matrices. The C18 phase is the most popular phase.  UCT offers a range of hydrocarbon chain lengths from C2 to C30. In addition, we offer isobutyl, tertbutyl, phenyl, and cyclohexyl bonded phases.

Compounds are retained on hydrophilic sorbents through polar interactions including hydrogen bonding, pi-pi or dipole-dipole interaction.  Compounds typically extracted on a hydrophilic column include analytes which have polar groups, including amines, hydroxyls and carbonyls. Elution is performed by strong polar solvents. For these types of extractions UCT offers various types of base silica, Florisil®, Alumina's, cyanopropy…
