This work in collaboration with Erin Baker titled “Uncovering PFAS and Other Xenobiotics in the Dark Metabolome Using Ion Mobility Spectrometry, Mass Defect Analysis, and Machine Learning” in Environmental Science & Technology identifies features specifice to PFAS, but reveals that there are still many unknowns in untargeted studies, but by incorporating xenobiotics more confident annotations can be achieved.
