CBA is a midpolarity sorbent and weak cation exchanger (pKa 4.8). It can be used with a wider range of counterions than lower pKa sorbents like SCX, and will demonstrate easier elution of quaternary amine functionalized analytes.
The Bond Elut Certify extraction cartridge utilizes a packed bed consisting of a special, nonpolar 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 extracting a wide range of compounds from a diverse number of aqueous matrices.
Bond Elut Certify II was developed specifically for the rapid and effective extraction of acidic drugs and metabolites from urine and other biological matrices. Certify II is a mixed-mode cartridge packed with nonpolar C8 and strong anion-exchange (SAX) sorbent. It has been optimized for acidic drugs, such as 11-nor-delta-9-tetrahydrocannibinol-carboxylic acid, salicylic acid, ibuprofen, acetaminophen, and other compounds tha…
Bond Elut CH is a midpolarity sorbent that exhibits unique selectivities for certain analytes. When employed as a nonpolar sorbent, CH has the approximate polarity of a C2 sorbent. Bond Elut CH is often a good choice when nonpolar sorbents, such as C18, C8, or C2, do not provide the desired selectivity.
A medium polarity sorbent with many uses, Bond Elut Cyano (CN) is ideal for applications in which extremely nonpolar compounds would be irreversibly retained on high carbon load sorbents, such as C8 and C18. This endcapped version of the cyano sorbent is best utilized when extracting analytes from an aqueous matrix.
Bond Elut DEA bears some resemblance to Bond Elut NH2 in its properties, but with a slightly lower capacity as an anion-exchange sorbent. DEA has a moderately nonpolar character due to the alkyl side chains on the amino functionality. These groups still afford a medium level of polarity, higher than C8, but less polar than C2 or CN-E.
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.
A variety of empty reservoirs is available to increase the sample capacity of Bond Elut extraction cartridges. These tubes can also be used to pack custom SPE cartridges with bulk Bondesil sorbents or other desired sorbent. They are available from 1 to 60 mL.
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.
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 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 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. 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.
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.
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.
