POLYSorb

POLYSorb from Concise are solid-phase extraction (SPE) cartridges. These cartridges are based on polystyrene/divinylbenzene (PS/DVB) and are available unmodified, with C18 groups or sulphonated. Due to the polymer used, these cartridges can be used in a wide pH range and show excellent selectivity even for trace analyses.
