Alix Rodowa is a Research Chemist in the Organic Chemical Metrology Group within NIST’s Chemical Sciences Division. Specializing in trace organic analysis and environmental metrology, she leads research tackling high-priority contaminants of commerce, with an emphasis on per- and polyfluoroalkyl substances (PFAS). Alix advances chromatography–mass spectrometry methods to quantify PFAS across critical matrices—including drinking water, food and agricultural products, and aqueous film-forming foams (AFFF). Her work contributes to the development of NIST Standard Reference Materials, establishing the measurement baseline needed to strengthen data integrity and quality and support U.S. commerce.
