Solid phase extraction cartridges, Bond Elut™ SCX

Supplier: VARIAN
Description: 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.

Solid phase extraction cartridges, Bond Elut™ NEXUS and NEXUS WCX

Supplier: VARIAN
Description: Bond Elut™ NEXUS is an ultra-clean polymeric sorbent which has bi-modal porosity and a high surface area. NEXUS offers a nonpolar retention mechanism with no pre-conditioning required. The large particle size makes NEXUS ideal for extractions from highly viscous samples, such as horse urine.

Based on the same base polymer technology, Bond Elut™ NEXUS WCX is a weak cation exchange sorbent that offers extra selectivity for analytes, such as quaternary ammonium drugs and anabolic steroids.

Solid phase extraction cartridges, Bond Elut™ PBA

Supplier: VARIAN
Description: PBA is a unique sorbent consisting of a phenylboronic acid covalently linked to a silica gel surface. Covalent processes result in a higher retention to the sorbent surface than other mechanisms, resulting in superior clean-up. The boronate group has a high specificity for cis-diol containing compounds such as catechols, nucleic acids, low molecular weight proteins and carbohydrates.

Solid phase extraction cartridges, Bond Elut™ SAX

Supplier: VARIAN
Description: 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.

Solid phase extraction cartridges, Bond Elut™ C2

Supplier: VARIAN
Description: 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 cartridges, Bond Elut™ C18

Supplier: VARIAN
Description: 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.

HPLC columns, Purospher® STAR RP-18 endcapped

Supplier: Merck
Description: Fast method development of complex samples across the pH range from 1,5 to 10,5 with different mobile phases and temperature conditions.
Purospher® STAR RP-18 endcapped HPLC columns are designed for universal use. Basic, neutral and metal-chelating compounds can easily be separated with simple mobile phases – naturally without peak tailing. Thanks to its outstanding performance and stability, Purospher® STAR RP-18 endcapped offers maximum flexibility in method development. Robust methods can be developed over the entire pH range from 1,5 to 10,5. High pH-stability allows the separation of strongly basic compounds with alkaline eluents. The combination of high purity silica, best all-round retention characteristics, outstanding pH stability up to pH 10,5, and suitability for up to 100% aqueous mobile phases, make Purospher® STAR RP-18 endcapped an all-round top performance column, almost universal in its range of applications.

Solid phase extraction cartridges, Bond Elut™ SI

Supplier: VARIAN
Description: 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.
