Presenter: Karl Oetjen, PhD (Senior Scientist, SCIEX)
Karl Oetjen is a Senior Technical Marketing Scientist for Food, Environmental, Forensic, Clinical and Cannabis applications at SCIEX. Before joining SCIEX, he completed his PhD at Colorado School of Mines (Golden, Colorado) in Hydrologic Science and Engineering under Dr. Chris Higgins. Karl’s dissertation research focused on nontarget characterization of complex surfactant mixtures, including aqueous film forming foams. This work led to the discovery several novel per- and polyfluorinated alkyl substances (PFAS) that since have been found in variety of environmental samples and industrial chemicals. Since joining SCIEX, Karl has worked with numerous labs creating and implementing both regulated and unregulated quantitative and qualitative screening methods.
