Final Progress Reports

Year:   2016 

The function of the Analytical Chemistry Core (ACC) is to provide routine sample analysis and monitoring of Superfund contaminants examined in individual biomedical and non-biomedical projects. Furthermore the Core provides analytical expertise in identifying degradation products and/or metabolites of these Superfund contaminants using high-resolution mass spectrometry techniques.

The Analytical Chemistry Core is an essential resource for Duke’s SRC. In the past year’s funding cycle, capabilities have grown to include non-targeted mass spectrometric analysis of contaminants in consumer products and household foam samples and enhanced HPLC-MS methods for project analytes. The ACC is integral in providing high-quality chemical analyses to all projects of Duke’s SRC. This analytical support has allowed researchers to explore new research questions, work with new Superfund contaminants and interact more readily with other projects. Specifically, researchers have successfully developed highly sensitive quantitative and qualitative methods for measuring Superfund-target compounds such as PAHs, halogenated flame retardants, organophosphate pesticides, and chlorophenols, along with their transformation products, in a variety of biological and environmental sample types. With the support of the ACC, Duke SRC researchers now have access to highly sensitive and specific mass spectrometry techniques, which expand the number of compounds under study as well as the range of concentrations that can be explored. Finally, over the past year they have continued to provide training for SRC researchers and students in analytical chemistry principles and practice. To date, the ACC has analyzed over 100 target analytes over 4,200 samples for Duke SRC researchers, across all four projects.
