Applications of Paper Spray-Based Mass Spectrometry Techniques for Rapid and Sensitive Detection of Per- and Polyfluoroalkyl Substances (PFAS)

Traditional PFAS analysis by mass spectrometry (MS) is time-consuming, as laborious sample preparation (e.g., extraction and desalting) is necessary. This invention reports fast detection of PFAS by paper spray (PS)-based MS techniques, which employs a triangular-shaped filter paper for sample loading and ionization (≤ 3 min per sample). PS-MS can...
