Descrizione: 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.

Descrizione: 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.

Descrizione: 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.

Descrizione: 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.

Descrizione: 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.

Descrizione: EnvirElut™ sorbents are specially designed for the extraction of a wide range of compounds from aqueous matrices. EnvirElut™ PAH and Pesticides are available in standard SPE straight barrel cartridges, which can be used on conventional vacuum manifolds such as the Vac Elut SPS 24.

Descrizione: 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.

Descrizione: Clean PP reservoirs contain two PP frits pre-inserted, an ideal configuration for simple filtration.

Descrizione: CBA is a mid-polarity sorbent and weak cation exchanger (pKa 4,8). It can be used with a wider range of counter-ions than lower pKa sorbents like SCX and will demonstrate easier elution of quaternary amine functionalised analytes.

Descrizione: The Bond Elut™ Certify extraction cartridge utilises a packed bed consisting of a special, non-polar 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 extraction of a wide range of compounds from a diverse range of aqueous matrices.

Descrizione: Bond Elut™ PH is a non-polar bonded silica material which exhibits a different selectivity to alkyl or aliphatic functionalised 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.
