Descripción: 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 non-polar 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.

Descripción: 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. The PSA functional group is a very effective bidentate ligand and is therefore an excellent sorbent for chelation applications. 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.

Descripción: Bond Elut™ Plexa PCX uses a polymeric cation exchange resin that combines the outstanding properties of Bond Elut™ Plexa - superior flow characteristics and improved analytical performance - with strong cation exchange functionalities. This mixed-mode SPE sorbent removes neutral and acidic interferences from the matrix, concentrates basic analytes and therefore improves sensitivity in the determination of basic compounds.

Descripción: Bond Elut™ Diol (2OH) resembles unbonded silica in its tendency for strong hydrogen bonding with analytes. 2OH can also be employed in the non-polar mode because the hydrocarbon spacer on its functional group provides enough non-polar character for retention of hydrophobic analytes. Bond Elut™ Diol is a listed SPE device for the DIN 14333-1 method on benzimidazole fungicides.

Descripción: The water-wettable, hydroxylated exterior allows excellent flow, even with biological fluids. A gradient of polarity on the polymer surface shunts small analytes to the more hydrophobic centre of the polymer bead, where they are retained prior to the washing and elution steps. Plexa provides these performance enhancements due to a unique polymeric architecture with a non-retentive, hydroxylated, amide-free surface and a non-polar PS/DVB core for retaining small molecules.

Descripción: 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 non-polar interactions. This non-polar characteristic becomes particularly important when conducting ion-exchange from aqueous systems, where selectivity towards compounds exhibiting cationic and non-polar character is seen.

Descripción: Bond Elut™ C18 is the most hydrophobic, bonded silica sorbent in the Bond Elut™ range. It is the most popular SPE sorbent because of its extremely retentive nature for non-polar compounds. C18 is generally regarded as having the broadest spectrum of retention among bonded silica sorbents, since it retains most organic analytes from aqueous matrices. When analysing small to intermediate molecules, Bond Elut™ C18 can be used for desalting aqueous matrices prior to ion exchange, as salts pass through the sorbent unretained.

Proveedor: Thermo Fisher Scientific
