Formatted Title
Analysis of Ultra-Short Chain PFAS
Background/Objectives
The presence of ultra-short chain PFAS in the environment has 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.
Approach/Activities
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.
Results/Lessons Learned
The author will present on the challenges these compounds represent, a brief description of the analytical methods, the data quality performance of the methods, and some applications thereof.
The presentation is designed for all members of the conference, and does not require a depth of understanding of chemistry or analytical methods.
