New Publication – Community Needs and Proposed Solutions for a Broadly Applicable Standard/QC Mixture for High-Resolution Mass Spectrometry-Based Non-Targeted Analysis

by

Check out this recent publication describing the results of a community survey to determine desired characteristics/uses for a non-targeted standard mixture! Many BP4NTA members (among others) contributed to this survey. The authors thank all respondents for providing valuable feedback!

Abstract: Non-targeted analysis (NTA) using high-resolution mass spectrometry (HRMS) is a global chemical screening approach that generates information-rich data which can be used to detect and identify unknown chemicals. NTA is a powerful approach which is increasingly being used for a variety of sample types, research fields, and goals. However, there are challenges associated with accurate assessments of data quality and method performance, comparability across laboratories/instruments/methods, and communication of results/confidence. A standard mixture containing a sufficient number and diversity of chemicals would help address these needs, but is not yet commercially available. Thus, we conducted a survey of 146 NTA researchers to examine desired requirements for the broad fields, studies, and goals where NTA can be applied. We also compare this feedback to previously published in-house standard mixtures, which, we argue, are models for a standard that can be adjusted to fit the NTA community’s needs and possibly commercialized. Reversed-phase liquid chromatography HRMS is one of the most common methods used for NTA; therefore, this survey is focused on characteristics necessary for these types of methods. We intend this information to communicate the need for an interdisciplinary NTA standard mixture, the importance of implementing standards, and to lower the barriers for chemical vendor standard mixture development and distribution.

April Meeting: Dr. Jaanus Liigand

by

Dr. Jaanus Liigand, co-founder and CEO of Quantem Analytics, will give a talk titled “Make your MS Analysis Quantitative Without Analytical Standards” and discuss with the membership their challenges, needs, and expectations for quantitative non-targeted analysis.

This meeting will occur on Tuesday, April 15th, from 12 pm – 1 pm EST.

Abstract: Quantification in non-targeted analysis remains a significant challenge due to the absence of analytical standards. Conventional approaches—such as the use of structural analogues or surrogate standards—often lead to high uncertainty. This seminar introduces Quantem, a machine learning-based solution that predicts ionization efficiency directly from molecular structure and analysis conditions. The method enables more reliable semi-quantification in suspect and non-targeted screening workflows, supporting better decision-making such as toxicity assessment or prioritizing which samples or compounds should undergo targeted analysis.
Comparative insights with traditional methods will be provided to highlight improvements in accuracy and applicability. Real-life case studies will demonstrate how predictive models can be effectively integrated into non-targeted analytical workflows.

ORD Scientists Publish Automated Quality Control Workflow for Non-Targeted Analysis (NTA)

The EPA’s Center for Computational Toxicology and Exposure’s (CCTE’s) team and additional EPA collaborators published a paper in Analytical and Bioanalytical Chemistry titled “Automated QA/QC reporting for non-targeted analysis: a demonstration of INTERPRET NTA with de facto water reuse data.” Comprehensive standards do not yet exist to guide NTA quality assurance/quality control (QA/QC) procedures. Furthermore, no single software tool meets the needs for QA/QC review and documentation. To address these needs ORD researchers created “INTERPRET NTA” (Interface for Processing, Reviewing, and Translating NTA data), and show utility on a case study of water reuse NTA data.

CCTE contributors: Jon Sobus, Nickolas Sayre-Smith (ORISE), Alex Chao, Troy Ferland (ORISE), Tyler Carr (ORISE), Heather Whitehead, Matthew Boyce (ORISE), Elin Ulrich, and Tony Williams
Additional contributors: CPHEA’s Jeff Minucci, CEMM’s James McCord; and CESER’s Laura Brunelle and Angela Batt

CCTE Scientists Contribute to Study of Quantitative NTA Estimates of PFAS

CCTE’s Shirley Pu (ORISE), Nickolas Sayre-Smith (ORISE), and Jon Sobus contributed to a study in Analytical and Bioanalytical Chemistry titled “Examining environmental matrix effects on quantitative non-targeted analysis estimates of per- and polyfluoroalkyl substances.” While NTA outputs are often qualitative, concentration estimation is now possible using quantitative non-targeted analysis (qNTA) approaches. This study used a set of 19 PFAS to examine the impacts of drinking water and waste-activated sludge matrices on qNTA performance. Results suggest that reliable qNTA studies must use carefully produced matrix-matched calibration data.

February Meeting: Ben Place

by

Ben Place, a Research Chemist within the Organic Chemical Metrology Group at the National Institute of Standards and Technology (NIST), will be giving a talk on “The NIST Per- and Polyfluoroalkyl Substances Interlaboratory Study – Exercise 1”. In addition to his work at NIST, Ben is one of the founding chairs of BP4NTA and the current leader of the BP4NTA Study Planning Tool working group.

This meeting will occur on Tuesday, February 18th, from 12 pm – 1 pm EST.

Abstract: As HRMS-based non-targeted analysis (NTA) techniques advance and become more routine, there is a significant need by the research community to understand the interlaboratory comparability of NTA methods and results. As part of a US Department of Defense-funded effort, researchers at NIST designed an interlaboratory study focused on the identification of per- and polyfluoroalkyl substances (PFAS) in three prepared extract samples. Thirty-four laboratories with experience performing NTA were shipped the samples with a standard reporting form; 27 of the participating laboratories submitted data by the deadline. The initial interpretation of the results show that laboratories reported a wide range of PFAS identities across all three samples and a range of identification confidence (using the Charbonnet et al. PFAS confidence of identification scale). The presentation will cover the design of the study goals and samples, the administration and process of the interlaboratory study, and the results of the study, along with some lessons learned and potential future studies.

New Publication – Filling the Gaps in PFAS Detection: Integrating GC-MS Non-Targeted Analysis for Comprehensive Environmental Monitoring and Exposure Assessment

by

The newest publication from our BP4NTA members highlights the untapped potential of gas chromatography–mass spectrometry (GC-MS) in non-targeted analysis (NTA) of PFAS. While LC-MS has dominated PFAS studies, these findings show that GC-MS covers a complementary chemical space, crucial for identifying novel and volatile/semi-volatile PFAS that LC-MS may miss.

✅ Less than 10% of known PFAS chemistry is predicted to be amenable to typical LC-MS analysis.
✅ GC-NTA is essential for uncovering unknown PFAS in waste streams, incineration byproducts, air emissions, and consumer products.
✅ Collaboration is needed to overcome challenges and advance GC-NTA in environmental research.

We call on researchers, grantors, and stakeholders to recognize and invest in GC-NTA as a critical tool for fully understanding PFAS contamination. Let’s push the boundaries of PFAS research together!
