Welcome to “Analytically Speaking,” the podcast from LCGC International and Spectroscopy. In this episode, podcast co-hosts Dr. Dwight Stoll and Dr. James Grinias talk with Dr. Mark Schure, who has worked in separation science for over 35 years in both industry and academia. Over a 28-year period, he worked for Digital Equipment Corporation, the Rohm and Haas Company, and the Dow Chemical Company. Since then, he has served as Chief Technology Officer for Kroungold Analytical, and he has been an adjunct professor in the Department of Chemical and Biomolecular Engineering at the University of Delaware for over 20 years. Dr. Schure is a widely recognized expert in separation science who has published more than 110 papers, holds numerous patents, and edited the book Multidimensional Liquid Chromatography. His scientific interests encompass the fundamental separation science of complex molecules, polymers, and colloids, alongside 2D chromatography, retention mechanisms, and field flow fractionation. He has received numerous accolades, including the Eastern Analytical Symposium Award in Separation Science and the Uwe Neue Award from the HPLC conference. In a wide ranging conversation recorded live at the HPLC 2026 conference in Indianapolis following a memorial session for Prof. Peter Carr, we explore Mark’s unique entry into separation science, which benefited from prior experiences building amplifiers and electronics before transitioning to write Fortran software as a consultant for chemists at Northeastern University. We then discuss Mark’s foundational simulation work in field flow fractionation (FFF), including his approaches to modeling Coriolis effects and sedimentation. We also spend some time talking about Mark’s pioneering theoretical contributions to 2D chromatography on topics including sampling rate and detection limits. Finally, Mark shares his perspective on the intense inter-diffusion of information between his modeling group and Pete Carr and Ilja Siepmann at the University of Minnesota, the future of analytical chemistry, the need for improved analytical strategies for complex matrices like exosomes, and the potential for artificial intelligence to help identify unknown compounds in complex mixtures.

Welcome to “Analytically Speaking,” the podcast from LCGC International and Spectroscopy. Here in Episode #47, podcast host Dr. Jerry Workman speaks with Dr. Thomas Mayerhöfer from the Leibniz Institute of Photonic Technology (Leibniz IPHT) in Jena, Germany, and Friedrich Schiller University Jena, about “the other half” of the Beer–Lambert law: dispersion theory, the concentration law of the refractive index, and refractive-index and complex-valued chemometrics. Dr. Mayerhöfer, who first joined the podcast for Episode #29 on the history and theory of infrared spectroscopy, returns to explain how Beer’s law falls out of dispersion theory as a limiting case, why the refractive index obeys a concentration law of its own that was mainstream physical chemistry before about 1920 (and helped confirm the Kekulé structure of benzene), and how new refractive-index and complex-valued chemometric methods — in combination with PLS — can outperform conventional absorbance-based calibration by up to an order of magnitude.

Accurate fluorine determination in organic matrices like polymers, fuels, and oils remains one of analytical chemistry's most persistent challenges. In this Dedicated Dialogue, Holger Sievers, PhD, Product Manager of Atomic Absorption Spectrometry at Analytik Jena, explains why conventional techniques fall short and introduces a novel approach that combines pyrohydrolytic combustion with high-resolution continuum source molecular absorption spectrometry. This method delivers faster, more sensitive, and more reliable fluorine measurement across a range of industries.

In this episode, podcast co-hosts Dr. Dwight Stoll and Dr. James Grinias talk with Professor Kelly Hines. Dr. Hines is an associate professor in the Department of Chemistry at the University of Georgia in Athens.

In this episode of Analytically Speaking, explore the intersection of forensic science and cannabis research with Brent Wilson as he shares insights on analytical chemistry and standards.

Sandra Wunsch, Application Specialist at Analytik Jena, gives us exciting insights into the analysis of bread for potassium bromate using spectroscopy and why the SPECORD PLUS is the best choice for this.

Creating uniform and repeatable monolayers is incredibly important for both scientific pursuits as well as the manufacturing of products in semiconductor, biotechnology, and. other industries. However, measuring monolayers and functionalized surfaces directly is. difficult, and many rely on a variety of characterization techniques that when used together can provide some degree of confidence. By combining non-contact atomic force microscopy (AFM) and IR spectroscopy, IR PiFM provides sensitive and accurate analysis of sub-monolayer of molecules without the concern of tip-sample cross contamination. Dr. Sung Park, Molecular Vista, joined Spectroscopy to provide insights on how IR PiFM can acquire IR signature of monolayer films due to its unique implementation.
