Per- and polyfluoroalkyl substances (PFAS) are used for many daily applications e.g. food packaging and textile coating because of their non-sticky properties. Most PFAS are hazardous substances which need to be monitored globally. Due to their increasing appearance in the environment new product solutions are of great demand. CHROMABOND PFAS provides such a solution for the enrichment of per- and polyfluoroalkyl substances (PFAS) from water.
In contrast to other products, this special phase enables users to enrich not only acidic PFAS but also various other PFAS substance classes (alcohols, sulfonamides, ethers) with high recovery rates in one application. This is possible due to the different retention mechanisms of the sorbents (interactions according to EPA method 537.1 and 533, DIN 38407-42).
The application note Solid phase extraction of per- and polyfluoroalkyl substances (PFAS) from drinking water shows the successful sample preparation (solid phase extraction) of PFAS from drinking water. The subsequent analysis was performed by NUCLEOSHELL RP 18plus HPLC column.
When conducting PFAS analysis, it is crucial to select the right vials and closures for this application. Adsorption effects of glass as well as possible contamination of the sample by particles from the septa, especially from the PTFE lamination, may put your analysis results at risk.
