I'm not too familiar with the LC/ms/ms we use for pfas analysis, but there was a discussion about contamination seen, precursor/transition ions 263.0 -> 218.9. This has apparently been narrowed down to the methanol used, however it's not every lot of methanol and sometimes not every bottle within the same lot. Anyone familiar with these ions and where they may originate from? Thank you.
