David S. Bell
Dr. David S. Bell is currently Lead Consultant and Owner at ASKkPrime, LLC a consulting firm focused in the separation science arena. Dave also serves on the Editorial Advisory Board for LCGC Magazine and is the Editor for the Column Watch series of articles.
Over the past three decades, Dave has worked directly in the chromatography industry, focusing his efforts on the design, development, and application of chromatographic stationary phases to advance gas chromatography, liquid chromatography, sample preparation and related hyphenated techniques.Prior to focusing on chromatography device development and application, he spent a decade immersed in the pharmaceutical industry performing analytical method development and validation employing various forms of chromatography and electrophoresis.
Dave’s main objectives have been to create and promote novel chromatography technologies and to conduct and collaborate on research aimed toward understanding molecular interactions that contribute to retention and selectivity in an array of chromatographic processes. His research results have been presented in hundreds of symposia worldwide, and have resulted in more than 95 peer-reviewed journal and trade magazine articles.His efforts have also contributed to the development and commercialization of numerous products utilized in laboratories worldwide.
Dave’s undergraduate studies in chemistry were completed at the State University of New York at Plattsburgh (SUNY Plattsburgh). He earned his PhD in Chemistry from The Pennsylvania State University (State College, Pennsylvania).

State-of-the-Art in Capillary Liquid Chromatography (LC): Now, Next, and How?
At the 43rd International Symposium on Capillary Chromatography (ISCC 2019) in Fort Worth, Texas, a panel addressed the current challenges and potential future directions in capillary liquid chromatography. How can their vision be achieved?
State-of-the-Art in Capillary Liquid Chromatography: Now, Next, and How?
The “State-of-the-Art in Capillary Liquid Chromatography” panel discussion at the 43rd International Symposium on Capillary Chromatography (ISCC 2019) in Fort Worth, Texas, USA, was a thoughtful dialogue on current challenges and potential future directions in the field. The session included a general overview of the current state of the field, key drawbacks preventing widespread use of capillary liquid chromatography (LC) columns, and how these challenges might be overcome. In this article, we highlight some of the common themes that were discussed as part of this panel.
Highlights from the HPLC 2019 Symposium
October 1st 2019The 48th International Symposium on High Performance Liquid Phase Separations and Related Techniques (HPLC 2019), chaired by Alberto Cavazzini and Massimo Morbidelli, was held from 16–20 June in Milan, Italy. This instalment of “Column Watch” covers many of the highlights observed at the symposium.
