Ep. 19: Atomic Spectroscopy: Searching for Life in all the Right Places


Welcome to “Analytically Speaking,” the podcast from LCGC and Spectroscopy.

Here in Episode #19, podcast host Dr. Jerry Workman speaks with Dr. Andreas Riedo about the new developments in atomic spectroscopy, particularly those related to new advances in the field of space research.

Dr. Riedo is a Scientist at the Physics Institute, Space Research and Planetary Sciences, at the University of Bern in Switzerland. He received his PhD in physics in 2014 and has been actively involved in the field of space research and planetary exploration since 2010. His work has included the design, development, and qualification of space-capable analytical instrumentation. His interest and work in the field of laser-based mass spectrometry began during his PhD studies with Prof. Peter Wurz at the Physics Institute in the division of Space Research and Planetary Sciences at the University of Bern. As a graduate student, Riedo optimized an existing LIMS system intended for in situ space research. The instrument has been enhanced to perform analysis for quantitative element composition, isotope abundances, depth profiling, and two- and three-dimensional chemical imaging and analysis. In recent years, Riedo developed the ORIGIN instrument consisting of the same mass analyzer used in his previous studies, but adapted for organic molecule detection. More information and links about Dr. Riedo and his research can be found within our podcast posting links.

More about our hosts:

Dwight Stoll, PhD:

Dwight R. Stoll is a professor of chemistry at Gustavus Adolphus College in St. Peter, Minnesota. He received his PhD from the University of Minnesota, under Professor Peter Carr, working on the development of fast, comprehensive two-dimensional liquid chromatography (2D-LC). Stoll’s current primary research focus is on the development of 2D-LC for both targeted and untargeted analyses. Active research projects in his laboratory touch on most aspects of multidimensional separation methodologies, including optimization strategies, characterization of selectivity in reversed-phase LC, instrument development, and applications in biopharmaceutical analysis. Stoll is the author or co-author of more than 80 peer-reviewed publications and six book chapters and has instructed numerous short courses in 2D-LC. In 2011 he was the recipient of LCGC’s Emerging Leader in Chromatography Award. In 2017 he received the Georges Guiochon Faculty Fellowship, and was recognized with an Agilent Technologies Thought Leader Award. He is also a member of LCGC’s editorial advisory board and is the editor of the “LC Troubleshooting” column in LCGC.

Jerome Workman, Jr., PhD:

Jerome (Jerry) J. Workman, Jr. is the Senior Technical Editor for LCGC and Spectroscopy. He has held positions as CTO, executive VP, senior research fellow, director, and senior scientist at companies of all sizes, from start-ups to world-leading corporations. He has been an adjunct faculty member of four universities and advised multiple graduate students. He has more than 75 U.S. and international patent applications and 30 issued U.S. and international patents and multiple trade secrets, as well as 500+ technical publications, and 20 reference book volumes on a broad range of spectroscopy and data processing techniques. He has received multiple awards from scientific societies, and has taught annual courses in spectroscopy, chemometrics, and statistics for the AOAC, ACS, ISA, FACSS, and at several universities and corporations. He is a Fellow of the American Institute of Chemists (FAIC), the American Society for Testing and Materials (ASTM), and the Royal Society of Chemistry in the UK (FRSC, CChem, CSci). Jerry holds B.A and M.A degrees from Saint Mary's University of Minnesota, and a PhD degree from Columbia Pacific University working in near-infrared spectroscopy. He is an alumnus of both Columbia University Business School and the MIT Sloan School of Management.
