Sam Lodge is the Phenomenex Senior Business Development Manager for the Environmental industry. He has been at Phenomenex for over 30 years in various positions, including Key Account Manager and Senior International Sales Manager, and is a product expert in SPE and HPLC chemistries. Over the past 8 years, he has worked extensively with commercial and government labs in the development and support of PFAS analytical methods, including the validation of EPA 533, the MLV for DM 1633, and many internal (MOD) methods. Sam was instrumental in the collaborations that led to the development of several new SPE formats for PFAS, including several different stacked tubes and pass-through GCB cartridges that can help commercial labs to increase productivity and reduce costs. In his spare time, Sam enjoys fishing and surfing (but not at the same time!)
Karl Oetjen is a Market Development Manager for Environmental, Industrial, Food & Beverage at SCIEX and has over 10 years of mass spectrometry experience. Before joining SCIEX, he completed his PhD at Colorado School of Mines (Golden, Colorado) in Hydrologic Science and Engineering. Karl’s dissertation research focused on nontarget characterization of complex surfactant mixtures, including aqueous film-forming foams. This work led to the discovery of several novel per- and polyfluorinated alkyl substances (PFAS) that have since been found in a 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.
Simon Roberts is a Staff Scientist at SCIEX and completed a postdoctoral fellowship at the Colorado School of Mines, where he worked with Dr. Christopher Higgins and Dr. Jennifer Field to identify novel classes of PFAS chemicals in aqueous film-forming foams (AFFFs). At SCIEX, Simon specializes in method optimization and data reporting, helping labs across the country set up PFAS and other environmental analytical methods.
