Determination of Aqueous Film Forming Foam (AFFF) Composition Using a Multivariate Analysis Approach in UNIFI Scientific Information System
Abstract
Utilize streamlined multivariate analytical tools to determine compositional differences between AFFFs subject to environmental release.

Benefits
Reviewing complex high resolution, nontargeted MSE datasets using workflows, filters, and views within an integrated scientific information system allows:

Screening for a theoretically unlimited number of compounds in a single injection.
Interrogation of data for the presence of unknown compounds of interest via filtering and statistical analysis.
Structural elucidation of isolated unknown compounds of interest.
Statistical tools to allow for isolation of unique markers.
Introduction
Introduction
Aqueous film-forming foams (AFFFs) have been implemented in military and commercial fire-fighting activities to extinguish flammable liquid fuels. However, the use of these formulations has inadvertently resulted

in the release of environmental contaminants due to migration from the site of application. The various formulations of AFFFs consist of numerous fluorocarbon and hydrocarbon compounds.1 Characterizing the common as well as unique components of AFFFs that are used is the starting point for tracking these constituents through various environmental and biological compartments. In this work, seven AFFF mixtures were analyzed with a data-independent acquisition approach (MSE), using Waters Xevo G2-XS QTof in order to obtain full spectral accurate mass data from which a multivariate analysis (MVA) approach could be taken to identify unique components within the mixtures.

The aim of these case studies is to identify the markers of interest in an easy workflow through the use of UNIFI software tools. Here, the use of built-in MVA functionality with EZ Info 3.0 software takes componentized data and enables rapid identification of markers associated with a particular sample. Markers are then elucidated using the Discovery Toolset and proposed identifications can be made in a streamlined and organized manner, using the approach described here.
