This project focuses on the development of advanced analytical techniques for the sampling and detection of organic compounds, including PFAS, natural organic matter (NOM), and proteins. Our goal is to establish new methods that are more accurate, faster, and/or innovative. By combining novel sampling techniques (e.g., aerosols and PFAS) with enhanced detection methods such as mass spectrometry and spectroscopy, we aim to lower detection limits and generate improved data for environmental protection and public health.
