Chromatography Forum of Delaware Valley Dal Nogare Award 2021

The talks in this Tuesday morning session highlight developments in the fundamental understanding of the chromatographic process.

The session begins at 8:40 am with a talk by the awardee, Apryll Stalcup of the School of Chemical Sciences at Dublin City University, on supra-analytical separation science. In separation sciences, the dynamic interaction between solute, mobile phase, and stationary phase masks a wealth of molecular information. A long-term scientific goal has been to understand the relationship between intermolecular interactions and chemical separations, independent of the separation platform. In this talk Stalcup will outline the evolution from traditional to chiral to ionic liquid–based separations and how the intermolecular interactions shaping the phase behavior of pure substances are reflected in the separation, which acts as a molecular amplifier of these interactions.

Next at 9:15 am, Luis Colón of the University at Buffalo, State University of New York, will talk on unconventional modification of silica particles for high performance liquid chromatography (HPLC). This talk explores the modification of silica particles for HPLC without the use of traditional silanization reactions. This presentation will highlight the production and physiochemical characterization of the differently modified silicas, and their initial chromatographic assessment after they are packed in HPLC columns.

Jeremy Glennon of the University College Cork will then discuss, at 9:50 am, fast core–shell separation with nanomolar detection at a boron-doped diamond electrode. In this talk, the coupling of electrochemical detection at a boron-doped diamond electrode (BDD) with core–shell chromatography is examined for the rapid nano-molar detection of targeted solutes such as phenolics, neurotransmitters, and microbial signaling molecules.

This will be followed by a presentation at 10:40 am by Susan Olesik of The Ohio State University on nanofibers for improved preconcentration, separation, and detection. This talk discusses moving toward separations that use minimal amounts of organic or hazardous solvents that would be highly beneficial for efficiency and the environment. Reducing solvents will require that separation devices be highly selective for the analytes of interests and the stationary phases should be made of materials that can be used for an extended period. Ultrathin layer chromatography (UTLC) has the potential of meeting these desired capabilities. This talk will illustrate the unique range of chromatographic selectivity, solid-phase extraction preconcentration applications, and improved performance of UTLC when used with mass spectrometry.

The session will wrap up with a talk at 11:15 am by Daniel Armstrong of the University of Texas at Arlington on new developments in the role and analysis of D-amino acids in human disease. Reports on free peptide- and protein-associated D-amino acids in living organisms are increasing tremendously. Their role in human disease and presence as biomarkers are beginning to be recognized. This talk emphasizes the analysis and interpretation of D-amino acids within a human health context.
