Twelve PFASs (standards purchased from
Sigma-Aldrich) were analyzed, i.e., C₃–C₅ and C₇–C₉ perfluoroalkyl carboxylates
(PFCAs), C₄, C₆, and C₈ perfluoroalkyl
sulfonates (PFSAs), perfluorooctane sulfonamide (FOSA), and 6:2 and
8:2 fluorotelomer sulfonates (6:2 and 8:2 FTSA). For quantification
as well as for quality assurance and control (QA/QC), eight mass-labeled
internal standards (ISs) (i.e., ¹³C₄-PFBA, ¹³C₂-PFHxA, ¹³C₄-PFOA, ¹³C₅-PFNA, ¹³C₂-PFDA, ¹⁸O₂-PFHxS, ¹³C₄-PFOS, ¹³C₈-FOSA, purities > 99%, Wellington Laboratories,
Guelph, ON) were also included. For details on the included PFASs
and their internal standards, see Table S1 in the Supporting Information.

The target PFASs comprised: six perfluoroalkyl carboxylates (PFCAs), namely perfluorobutanoate (PFBA), perfluorohexanoate (PFHxA), perfluorooctanoate (PFOA), perfluorononanoate (PFNA), perfluorodecanoate (PFDA), and perfluoroundecanoate (PFUnDA); two perfluoroalkyl sulfonates (PFSAs), namely perfluorohexane sulfonates (PFHxS) and perfluorooctane sulfonates (PFOS); and one perfluorooctanesulfonamide (FOSA) (purity >99%, Wellington Laboratories, Guelph, ON). A total of nine isotopically labeled internal standards (IS) were used: ¹³C₄-PFBA, ¹³C₂-PFHxA, ¹³C₄-PFOA, ¹³C₅-PFNA, ¹³C₂-PFDA, ¹³C₂-PFUnDA, ¹⁸O₂-PFHxS, ¹³C₄-PFOS, and ¹³C₈-FOSA (purity >99%, Wellington Laboratories, Guelph, ON).

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
