Sarah is a Master's student in Environmental Engineering at the Colorado School of Mines. Her academic interests include remediation, contaminant fate and transport, and groundwater hydraulics. Most of her research has focused on poly- and perfluoroalkyl substances (PFASs) under the direction of Dr. Chris Higgins. She is passionate about environmental issues and water resources, and excited for a career in environmental engineering. In her spare time, she enjoys whitewater kayaking in the summer and skiing in the winter.


STUDENT POSTER PRESENTATION
Development of HRMS Spectral Library for Identification of Novel PFAS

While more attention has been paid in recent years to “novel” PFASs, many have not been extensively studied. Some have only been discovered in the past few years, and more are still in the process of being discovered through non-target analysis. In an attempt to increase the ability to detect and identify novel PFASs, fragmentation spectra for approximately 300 compounds, not found in the commerically available SCIEX library, were acquired and added to an internal library from AFFFs, neat standards, commercial products, and environmental samples using LC-QTOF-MS. Development of the HRMS spectral library has been an ongoing, collaborative effort, with scientists from all over the world sharing their samples for spectra collection, and with the library in turn being shared with scientists all over the world for use in research. A more complete spectral library will increase the global scientific community’s understanding of PFAS in the environment.
