Summary
Key numbers
Source-reported values checked against the cited page of the filed PDF. Values are reported as printed, without conversion. These are selected records, not an exhaustive transcription.
No values from this source are published. It is filed as method or context evidence.
Evidence Fitness
method_context. Accepted manuscript. Method and filler context only; no experimental spike or talc value is routed as carton PFAS occurrence.
Methods (brief)
Combustion ion chromatography and fluorine-19 solid-state NMR distinguish inorganic fluorine interference from organic fluorine; coated paper and talc experiments in PDF pp.3-6.
Analytes or measurement scopes: TF, TOF, PFOA, inorganic fluoride. Target identities are not inferred from the manifest acronym scan.
Limitations
No occurrence finding selected. Detection capability depends on acquisition and extraction; do not treat a method performance level as product content.
Selected rows are a bounded extraction, not a complete transcription of every table. Supplied main articles are the evidence boundary; unstaged supplements were not retrieved. Aggregate fluorine, targeted PFAS, migration, material content, detection frequency and modeled exposure remain distinct. All findings remain HOLD pending Elon verification.
