Abstract

Presentation title 1: Analysis of Ultra-Short Chain PFAS Abstract 1: The presence of ultra-short chain PFAS in the environment have been of recent concern due to their widespread use as replacements for longer chain PFAS. Traditional PFAS analysis has been primarily focused on compounds containing four or more carbon atoms. Historically, these compounds have been the most widely studied in terms of environmental contamination and toxicity. Additionally, measurement of smaller or more polar PFAS compounds is not compatible with existing EPA methods for PFAS analysis, and, thus, most laboratories have not investigated options for their analysis. "Demand for analytical methods that can generate data of the same quality for these compounds as published EPA methods for PFAS analysis has grown in recent years, with particular interest being shown in the analysis of TFA and PFPrA. This presentation will discuss the solution that Enthalpy Analytical has developed for this class of compounds and the unique challenges they present. This procedure focuses on the analysis of 11 such compounds, including two compounds that have two polar functional groups, which makes their analysis especially challenging. Presentation title 2: PFAS Analytical Methods and Sampling Techniques Abstract 2: As the analytical landscape continues to change with PFAS testing, having a clear understanding of the available analytical methods and their applicability becomes increasingly critical for operators, consultants, and regulators. With ever increasing analyte lists, method options, and types of matrices to be tested, the complexity around which method to choose can be daunting. Finding a single, reliable resource to provide this information can be even more challenging. This presentation will provide a high-level overview of the following: the chemistry and history of PFAS, the various analytical methods currently available and key differences among them, method applicability, and best practices when sampling. A clear explanation of how to apply each method in order to develop a conceptual understanding will be given, as well as how to evaluate historical data against newer methods that may be available. The presentation will also touch on best practices regarding sampling techniques, as well as tips on how to optimize the overall lab experience.
