In this episode, podcast host Dr. Dwight Stoll talks with Dr. Richard Henry, an expert in HPLC column technology who has had a long and productive career in the HPLC column business. They discuss Dr. Henry’s early experiences with analytical chemistry and liquid chromatography working for DuPont and Spectra-Physics, and eventually the launch and success of the company he founded in 1985, Keystone Scientific. He shares his perspectives on the evolution of LC column technology since the 1970s, his current interest in HILIC columns and separations, and the interactions between separation science and the chemistry of the environment. Finally, Dr. Henry shares some advice for young scientists, drawing on years of observation and his own experiences with failure and success.

Ep. 10: From the Ground Floor to HILIC – A Life in the HPLC Column Business

In this episode, podcast host Dr. Dwight Stoll talks with Dr. Steven Ray Wilson, a professor in the Department of Chemistry at the University of Oslo, Norway. Dr. Wilson is an expert in bioanalysis and has developed many innovative approaches for targeted and untargeted analysis of biomolecules, often in complex matrices such as biofluids. Most recently he has worked at the forefront of the rapidly growing field involving the use of organoids to better understand the biochemistry and physiology of organs by directly interrogating them with analytical techniques including separations and mass spectrometry. In the conversation, Dr. Wilson shares his thoughts on a broad range of topics including the opportunities that organoid analysis presents, the potential for organoids to influence environmental chemistry, publishing on pre-print servers, and more.

Ep. 12: Hyphenating Organoids with Chromatography

In this episode, podcast host Dr. Dwight Stoll talks with Dr. Emanuella Gionfriddo, associate professor in the Department of Chemistry at the University of Toledo, Ohio. Dr. Gionfriddo is an expert in bioanalysis and analyte extraction technologies, and works on both the development of new technologies, and the application of those technologies to contemporary analytical challenges. In their conversation, they discuss the origins of Dr. Gionfriddo’s interest in science, and several recent papers, including topics including extraction of neurotoxins from water, markers of hydraulic fracturing activity in wastewater, and development of thin-film extraction for improved performance of DNA amplification assays. Finally, Dr. Gionfriddo shares several pieces of advice for young and aspiring scientists.

Ep. 14: The more diverse is your toolbox, the more analytical problems you can solve

In this episode, podcast co-hosts Dr. Dwight Stoll and Dr. James Grinias talk with Dr. Benjamin Garcia. Dr. Garcia is the Raymond H. Wittcoff Distinguished Professor and Head of the Department of Biochemistry and Molecular Biophysics in the School of Medicine at Washington University in St. Louis. His research interests primarily focus on the development of mass spectrometry-based proteomic approaches for the analysis of post-translational modifications of proteins (PTMs) and modified proteomes. His group specializes in high-throughput and quantitative analysis of many classes of modified proteins, especially epigenetic histone PTMs. He is a prolific author and scientific leader, with an h-index approaching 120. He has received a LOT of awards to date, but we sat down with him at the Eastern Analytical Symposium where he was recognized for his recent EAS Award for Outstanding Achievement in Mass Spectrometry.

In the conversation we talk about the origins of Dr. Garcia’s interests in analytical science, mass spectrometry, and biomedical research, and he shares his thoughts about the current state and near future for technologies used for biomolecule separations including peptides, proteins, and oligonucleotides. We also discuss Dr. Garcia’s highly impactful efforts to promote participation in the analytical sciences by people from all backgrounds, and he shares some thoughts about the “to-do list” for his upcoming term as chair of the ACS Division of Analytical Chemistry.

Ep. 32: Don’t skip seminar…you might miss a life-changing event

Analytically Speaking, the podcast from LCGC and Spectroscopy magazines, addresses important issues in separation science and analytical spectroscopy. Topics include new analytical techniques, methods, and approaches; the latest trends; advances in instrument and software technology; practical solutions for specific applications; recent papers in the scientific literature and their applicability; challenges and solutions for data analysis and interpretation; analytical chemistry theory and fundamentals (from advanced research to tutorials and troubleshooting); and more. Our regular hosts are Dwight Stoll, PhD, a professor of chemistry at Gustavus Adolphus College in St. Peter, Minnesota, and Jerry Workman, PhD, a spectroscopist, noted author, and currently the Senior Technical Editor of Spectroscopy and LCGC. Dwight covers separation science and Jerry addresses spectroscopy related topics.
