Sec./tert. ammonium modified spherical polystyrene/divinylbenzene copoloymer, weak basic anion exchanger (mixed mode)Especially for the enrichment of PFAS.
The ROTI®XBond PFAS columns are specially optimized for the analysis of per- and polyfluoroalkyl substances (PFAS). PFAS have been used for over 60 years in various applications and are released into the environment during manufacturing, usage, and disposal. With increasingly stringent regulations in both the European Union and the United States—mandating the monitoring of PFAS levels in drinking water—the demand for reliable analytical methods is growing. Conventional WAX SPE columns often yield unsatisfactory results, whereas the new ROTI®XBond PFAS column is optimized and thoroughly tested for this application.
