Pesticide, Herbicide and PAH Extraction      EnvirElut sorbents are specially designed for the extraction of a wide range of compounds from aqueous matrices. EnvirElut Herbicides, PAH and Pesticides are available in standard SPE straight... Read more...

High Purity, Economical Alumina Sorbents   Alumina, like silica, is an extremely polar sorbent. The alumina surface tends to be slightly more stable under high pH conditions than unfunctionalized silica. The small particle size of the Bo... Read more...

The Universal, Non-polar SPE Sorbent   Bond Elut C18 is the most hydrophobic, bonded silica sorbent available in the Bond Elut range. It is the most popular SPE sorbent because of its extreme retentive nature for non-polar compounds. C18... Read more...

Agilent offers dispersive kits with sorbents and salts supplied in 2 mL or 15 mL centrifuge tubes to accommodate the aliquot volumes specified by current AOAC and EN methodologies. Select the Dispersive SPE kit suited to the type of food b... Read more...

Rapid Extraction of Acidic Drugs   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 pack... Read more...

Less Retention Than C8      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 ... Read more...

Extraction of Analytes From Urine   Bond Elut AccuCAT cartridges are mixed bed SPE cartridges consisting of a strong cation exchange (SCX) and a strong anion exchange (SAX) sorbent packed into one bed. AccuCAT is effective for the extrac... Read more...

Strong Cation Exchanger   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 inter... Read more...

Pi-pi Selective Non-polar Extractions      Bond Elut PH is a non-polar bonded silica material which exhibits a different selectivity to alkyl or aliphatic functionalized phases such as C8 or cyclohexyl. The electron density present in th... Read more...

New performance standard in analyte cleanup and reproducibility     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 ... Read more...

Unique Selectivity   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 choi... Read more...

Bond Elut Quality in a 96 Round-well Plate   Conversion of cartridge-based methods to an automation friendly 96-well format has never been easier or faster. The same trusted silica-based sorbents in Bond Elut cartridge products are now a... Read more...

Elution with No Need for Modifiers, Buffers or Acids   Bond Elut LMS polymeric sorbent lets you elute without having to add amine modifiers, buffers, or acids. The elimination of secondary interactions means that elution of analytes can ... Read more...

Medium Polarity Sorbent     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... Read more...

Retains Even the Most Polar Analytes   Bond Elut PPL is a styrene-divinylvernzene (SDVB) polymer that has been modified with a proprietary non-polar surface. PPL will retain even the most polar classes of analytes, including phenols. The... Read more...

Retention of Very Strong Anions      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 su... Read more...

Covalent Retention Affords Complete Clean up   Bond Elut PBA is a unique silica SPE sorbent containing a phenylboronic acid functionality that can retain analytes via a reversible covalent bond. This very strong covalent retention mechan... Read more...

High Polarity Sorbent   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 solve... Read more...

Balanced Retention of Polar Analytes   Bond Elut C18 OH is a non-endcapped 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 ... Read more...

Strong Anion Exchanger   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. Read more...
