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.

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.

Elena Hagemann, Product Manager for Process Spectroscopy at Metrohm USA, discusses a novel synchronized, automatic calibration data collector. This system eliminates the laborious calibration process of prediction model development without manual sampling. This capability allows moisture measurement systems to be calibrated at the factory down to approximately 7 ppm and to be installed in pipelines and reactors without additional calibration effort.
