Polymer based ASPEC® X-SCX solid phase extraction (SPE) cartridges contain a high-quality, polystyrene-divinylbenzene copolomer functionalized by a strong cation exchanger used for extraction of basic drugs and metabolites (pKa 7-9) from biological fluids and tissues.
ASPEC pre-capped cartridges are 'ASPEC instrument-ready', saving your time and money by eliminating manual capping. Thanks to automation that delivers consistent flow rates, these cartridges provide high loading capacity, accurate elution properties, and reproducible separation with low solvent usage. These cartridges are also available uncapped for manual extractions.
