Analytically Speaking LCGC & Spectroscopy

In this episode, podcast co-hosts Dr. Dwight Stoll and Dr. James Grinias talk with Dr. Andre de Villiers, Professor of Chemistry at Stellenbosch University in South Africa. Dr. de Villiers is an expert in multi-dimensional chromatography and leads a research program mainly focused on the use of two-dimensional liquid chromatography coupled with mass spectrometric detection for the deep characterization of natural products such as tea, wine, wood, and cocoa. Some of his recent work has explored the potential for ion mobility separations to increase the utility of mass spectrometric detection coupled with two-dimensional liquid chromatography separations.

In the conversation, we talk about the development of Andre’s interest in separation science as a result of a chance meeting with Pat Sandra, and the increasingly apparent “perception problem” facing the field of analytical chemistry. Finally, Dr. de Villiers shares his views on some of the most pressing challenges he sees in the work he is doing right now, including the need for better methods to separate complex mixtures of tannins in natural products, and the need for better data analysis tools in multi-dimensional separations in general.

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

Here in Episode #23, podcast host Dr. Jerry Workman speaks with Dr. Art Springsteen and Dr. David Wyble about the challenges of creating color standards and making color measurements using optical spectroscopy.

In this episode, podcast host Dr. Dwight Stoll talks with Dr. Katelynn Perrault Uptmor, Dr. Pierre-Hugues Stefanuto, and Dr. Petr Vozka about the multidimensional chromatography workshop, better known as the MDCW for short. Kate, PH, Petr, and Dwight are co-organizers of the MDCW workshop, which was held most recently at California State University, Los Angeles. In their conversation they discuss how the MDCW is different from, and similar to, conventional scientific conferences. They reflect on the most recent (15th) meeting, including highlights from both the technical and social programs, and in the impact on the local student community at Cal State LA. Then, they switch gears and look forward to the 16th MDCW, which will be held February 3-5 at the University of Liege, in Liege, Belgium.

Here in Episode 21, podcast host Dr. Jerry Workman speaks with Dr. Art Springsteen about the history and challenges associated with reflection and color standards used around the world for optical spectroscopy.

In this episode, podcast co-hosts Dr. Dwight Stoll and Dr. James Grinias talk with Dr. Heather Bean, Associate Professor of Biomedicine and Biotechnology at Arizona State University. Dr. Bean is an expert in volatilomics and leads a research program focused on the use of omics approaches to better understand a variety of physiological conditions ranging from disease and illness, such as cystic fibrosis and Valley fever, to fatigue. In their conversation, they discuss several of Dr. Bean’s recent research articles focused on the use of two-dimensional gas chromatography coupled with mass spectrometry to profile hundreds of volatile compounds present in biological samples that are relevant to these conditions. In addition to aspects of the actual separations that produce these data, they also discuss some of the current challenges in this type of work, including “missingness” in the datasets, and the importance of retention databases to omics work.

Listeners are also referred to the upcoming Multidimensional Chromatography Workshop, which will be held at California State University, Los Angeles, from January 10-12. For more information, see the conference website - http://www.multidimensionalchromatography.com/.

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.
