Extraction and Analysis of Per- and Polyfluoroalkyl Substances (PFAS) from Meals Ready-to-Eat (MRE) Films Using GC-MS and LC-MS/MS

OBJECTIVE: This work was in response to the Defense Logistic Agency’s (DLA) Subsistence Network Broad Agency Announcement, BAA-0003-16 addressing 2019 NDAA Section 329 that states packaging materials used for Meals Ready-to-Eat (MRE) that contact food products must be free of per- and polyfluoroalkyl substances (PFAS). This was addressed by determining the presence or absence of PFAS on MREs by extraction followed by gas chromatography mass spectrometry (GC-MS) and liquid chromatography tandem mass spectrometry (LC-MS/MS). Any samples positive for PFAS were quantitated using LC triple quadrupole (QqQ) MS at the US Army Engineering and Research Development Center (ERDC) and by high resolution quadrupole time-of-flight (qTOF) MS and GC-MS at Oregon State University (OSU).

Optimization of LC-MS/MS Parameters for Analysis of Per- and Polyfluoroalkyl Substances (PFAS)

Purpose: Integrate US Environmental Protection Agency (USEPA) Method 537 on current instrumentation to provide per- and polyfluoroalkyl substances (PFAS) analytical capabilities for the US Army Engineer Research and Development Center (ERDC), US Army Corps of Engineers (USACE) and the Department of Defense (DoD).
