Please join us for our monthly meeting on November 18th, 12 pm EST. Our speaker, Michael Rush, is a Distinguished Chemist at Edwards Lifesciences, specializing in advanced mass spectrometry and non-target analysis. As co-chair of the BP4NTA E&L technical subcommittee, Michael drives best practices and workflow harmonization to improve reproducibility and innovation in chemical characterization
Abstract: Non-targeted analysis (NTA) continues to evolve as a critical tool for comprehensive chemical characterization, particularly in complex matrices such as medical device extractables and leachables (E&L). Recent work, including our publication in Analytical Chemistry (DOI: 10.1021/acs.analchem.5c04247), demonstrates how advanced mass spectrometric workflows can improve reliability and reproducibility in E&L studies. This research highlights issues with quantitation strategies for medical device biocompatibility.
A second focus of this presentation will be communicating confidence in identifications—a cornerstone for regulatory acceptance and scientific transparency. We will explore the ISO10993-18 and FDA draft guidance in respect to how Edwards reports confidence levels in identifications.
Finally, we will provide an update on the BP4NTA E&L Technical Subcommittee, which aims to harmonize best practices for NTA in E&L testing. The subcommittee’s initiatives include integrating regulatory guidance, promoting collaboration across industry and academia, and developing educational resources to support newcomers and experienced practitioners alike. These efforts seek to advance reproducibility, foster innovation, and strengthen community standards for non-targeted workflows.
We are pleased to have three excellent candidates running in the 2025 election for BP4NTA steering committee members! All paid members are eligible to vote and will receive an email with voting instructions. Due to complications with website upgrades creating difficulties with membership renewals this year, anyone with a paid membership as of September 1, 2025 or later is eligible to vote in 2025. Though the election this year is not competitive, we still require a quorum of eligible voters to participate in order to appoint the new steering committee members. Get you votes in!

Please join us for our monthly meeting on September 16th, 12 pm EST. Our featured speaker is Jeremy Koelmel, an Associate Research Scientist in Epidemiology at the Yale School of Public Health, who will present on “Non-Targeted Analysis in Exposomics: Global Perspectives from the NEXUS International Survey.”
Abstract: In this presentation, we will discuss the essential role of non-targeted analysis in exposomics, and assess the multi-omics landscape of measurement science covering: lipidomics, metabolomics, xenobiotics, adductomics, and other approaches. Results are based on a survey conducted with over 150 participants (including a large presence of BP4NTA members!) and consisting of over 200 questions, giving both high-level and granular information pertaining to multi-omics analysis. Results we will cover include the types of matrices analyzed, instrumentation and software used, and chemical coverage. Community strategies in sample preparation, acquisition, and data-processing methods will also be discussed. Beyond the survey we will also discuss other Network for EXposomics in the U.S. (NEXUS) initiatives including the development of training materials for non-targeted analysis and exposomics and a user-friendly platform for processing non-targeted analysis data. NEXUS is a U24 Center for Exposome Research Coordination. NEXUS serves the broad biomedical research community by coordinating and advancing exposome research. The Center engages existing and ongoing exposome initiatives around the globe to promote methodological advancement and best practices, provide training and education, and foster national and international collaborations.

Please join us for our monthly meeting on August 19th, 12 pm EST. Our featured speaker is David Weil, a Master Applications Scientist at Agilent who will present on “Challenges and Best Practices for Extractable and Leachable Nontargeted Analysis”
Abstract: Extractable Leachable (E&L) analysis is just one of the many application areas that currently utilize nontargeted data analysis workflows. As pointed out in the recent publication from the BP4NTA group, E&L analysis faces many challenges starting with the complex nature of polymer extract samples and ending with compound identification. The talk will start by giving a brief overview of E&L analysis; then overview the regulatory landscape and recent push for standardization, emphasize how “good” chromatography matters to reduce false positives and enhance separation/sensitivity and wrap up by talking about methods to improve compound identification leveraging third-party online content. During the talk I will be give “Tips and Tricks” on ways to improve the quality of data being collected (MS and MSMS modes) and examples of where NTA required manual intervention.

Please join us for the monthly BP4NTA meeting on July 22 at 12 pm US Eastern Time. Note that this is delayed a week from our normal schedule due to a speaker conflict! The Zoom link was sent out in an email to all BP4NTA members. Please email BP4NTA directly if you’d like access and have not received the email. Our featured speaker is Carrie McDonough, who will present on her work on PFAS using high-resolution mass spectrometry (HRMS), ion mobility spectrometry (IMS), and FluoroMatch
Abstract: We are continuously exposed to mixtures of per/polyfluoroalkyl substances (PFASs) via drinking water, diet, indoor dust, and commercial products. These mixtures include highly persistent perfluoroalkyl acids (PFAAs) and their precursors. There are thousands of PFAS precursors (i.e., PFASs that can be transformed via environmental and biological processes to form PFAAs) with a wide range of physical/chemical properties. However, few of these compounds are available as neat standards, which are necessary for unequivocal identification, quantification, and toxicity assays. Here, I will discuss our work using in vitro and in vivo techniques applied directly to complex PFAS mixtures containing known and unknown PFASs. These techniques enable us to identify, prioritize, and assess bioaccumulation potential of novel PFASs that are overlooked by traditional monitoring methods. I will also discuss recent results from our work using high-resolution mass spectrometry (HRMS), ion mobility spectrometry (IMS), and the open-source software FluoroMatch to characterize these PFAS mixtures and track compositional changes between external exposure and internal dose. These approaches were used to characterize serum, urine, kidney, and liver tissue from mice dosed via gavage with an electrochemically-fluorinated aqueous film-forming foam (AFFF). N-glucuronidated C4-C6 perfluoroalkyl sulfonamides (N-glu-FASAs) were identified in urine excreted throughout the dosing study, highlighting glucuronidation as a significant chain-length-dependent excretion pathway for FASAs and substituted FASAs after dealkylation. Chromatographic patterns and drift time spectra suggest that doubly glucuronidated FASAs were also formed and excreted in urine. Longer-chain (>C8) FASAs primarily accumulated in liver and kidney tissues and were not detected in post-depuration serum. Some examples of applications of these techniques to prioritize detection of novel PFASs in challenging trace-level samples and complex environmental mixtures will also be discussed.
