Beskrivning: 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.

Beskrivning: 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.

Beskrivning: 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.

Beskrivning: Polaris™ amide C18 has the greatest polarity of the Polaris™ C18 family. The amide polar groups offer a different selectivity from either the C18-A or C18-ether phases. The surface has been covalently modified with alkyl amide groups and endcapped.

Beskrivning: Bond Elut™ CH is a mid-polarity sorbent that exhibits unique selectivities for certain analytes. When employed as a non-polar sorbent, CH has the approximate polarity of a C₂ sorbent. Bond Elut™ CH is often a good choice when non-polar sorbents such as C₁₈, C₈ or C₂ do not provide the desired selectivity.
