  • The reporting limit of a method is also dependent upon the consistency of clean blanks and elimination of sporadic contamination.
  • Vendors of PFAS consumables need to provide certified, trace level PFAS free products.
  • PFAS are everywhere!  They are widely used, vendors/suppliers when contacted don't know their processes are using them.
  • Since PFAS contamination has become an issue with PFAS analysis all field samples are taken in duplicate, not just field blanks. 
  • The complete data package and replicates need to be evaluated by the user in order to make sound conclusions and identify false positives. 
  • Every step there is a chance to incorporate “free-range” PFAS in your sample, minimize the preparation steps
