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 extraction of acidic, basic, and neutral analytes from urine and other biological samples. AccuCAT is particularly effective for catecholamine extraction from biofluids.
The Bond Elut Certify extraction cartridge utilizes a packed bed consisting of a special, nonpolar 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 extracting a wide range of compounds from a diverse number of aqueous matrices.
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 packed with nonpolar C8 and strong anion-exchange (SAX) sorbent. It has been optimized for acidic drugs, such as 11-nor-delta-9-tetrahydrocannibinol-carboxylic acid, salicylic acid, ibuprofen, acetaminophen, and other compounds that possess both nonpolar and anionic characteristics.
