Professor Emeritus, University of Michigan

Title:

Microscale Gas Chromatography (uGC) with Microsensor Array Detection: Challenges and Prospects

Abstract:

The capability to analyze complex mixtures of airborne volatile organic compounds (VOC), in situ, has implications for environmental monitoring, personal exposure assessment, biomedical diagnostics, and population security.  It is now clear that microsensor arrays, alone, lack this capability, and that upstream separation of mixture components is required. Although more than four decades of research and development of microscale gas chromatographic (mGC) systems has led to significant advances, many challenges remain. This talk will review the state-of-the-art in mGC with microsensor (array) detection for VOC mixtures, and the trade-offs in size, power, speed, sensitivity, and selectivity that constrain the available options.  Drawing on examples from our own work and that of other groups around the world, we will critically assess current approaches and discuss the prospects for expanding the complexity of mixtures that can be effectively analyzed with compact, even wearable, mGC systems. 

Bio:

Prof. Zellers has been involved in research on chemical microsensors and micro-instrumentation for volatile organic compounds for over 35 years, with particular interests in the design and physicochemical characterization of devices, materials, and systems related to the capture, preconcentration, separation, and sensing of multi-vapor mixtures of interest in occupational and environmental health sciences. He has published >140 articles and has several patents concerned with miniaturized and microfabricated devices and instrumentation for near-real-time monitoring of air contaminants.  He earned a bachelor’s degree in chemistry from Rutgers University and worked at Bell Laboratories as a synthetic chemist for several years prior to earning his master’s and doctoral degrees in environmental health sciences at UC Berkeley.  He then joined the faculty at the University of Michigan in 1987 and was appointed as a Professor in the Department of Environmental Health Sciences and in the Department of Chemistry before transitioning to Emeritus status in 2021.  From 2000-2016, he was the Leader of the Environmental Sensors and Systems Thrust in the Michigan Center for Wireless Integrated MicroSensing and Systems (WIMS2).  While currently engaged in a number of pursuits directed toward developing his right brain characteristics, he continues to serve the academic and professional scientific communities through various consulting assignments and a range of service activities.

Student and Early Career Professional Poster Session

Each Spring since times long past, the CFDV has invited young scientists to showcase their work at our annual symposium. Successful presenters have come from a surprising range of backgrounds and have typically demonstrated a high degree of passion, creativity and skill in their work. The symposium brings together leading experts in separation sciences from academia and industry, so the poster session provides presenters with a great opportunity to discuss their research and applications, get feedback on their projects, develop important career skills and build their professional network. On top of all that, a total of $500 in awards will be granted to presenters for the top three outstanding projects!
