Stephen Weber Wins Chromatography Forum of the Delaware Valley Dal Nogare Award
The 2016 Chromatography Forum of the Delaware Valley Dal Nogare Award was presented to Stephen Weber, professor of chemistry and clinical translational science at the University of Pittsburgh, at Pittcon 2016, held this year in Atlanta, Georgia.
The 2016 Chromatography Forum of the Delaware Valley Dal Nogare Award was presented to Stephen Weber, professor of chemistry and clinical translational science at the University of Pittsburgh, at Pittcon 2016, held this year in Atlanta, Georgia. The award was presented by Mary Ellen McNally of EI DuPont de Nemours and Company. Weber received his PhD in 1979 from McGill University for studying the theory and application of the electrochemical detector. His research involves analytical separations theory and application, and chromatographic detection and quantitation in bioanalytical chemistry, with a focus on neurochemistry. The Chromatography Forum of the Delaware Valley selects award recipients based on their contributions to the fundamental understanding of the chromatographic process. The award was established in honour of Stephen Dal Nogare, who died in 1968 after serving for six months as president of the Chromatography Forum.
The Complexity of Oligonucleotide Separations
January 9th 2025Peter Pellegrinelli, Applications Specialist at Advanced Materials Technology (AMT) explains the complexity of oligonucleotide separations due to the unique chemical properties of these molecules. Issues such as varying length, sequence complexity, and hydrophilic-hydrophobic characteristics make efficient separations difficult. Separation scientists are addressing these challenges by modifying mobile phase compositions, using varying ion-pairing reagents, and exploring alternative separation modes like HILIC and ion-exchange chromatography. Due to these complexities, AMT has introduced the HALO® OLIGO column, which offers high-resolution, fast separations through its innovative Fused-Core® technology and high pH stability. Alongside explaining the new column, Peter looks to the future of these separations and what is next to come.
Investigating Plastic Contamination in Olive Oil with GC–MS/MS
January 17th 2025The objective of this study was to investigate contamination by 32 plasticizers in olive oil throughout its production and packaging process. Separation and detection were carried out by gas chromatography tandem mass spectrometry (GC–MS/MS), without the need for pre-concentration steps.
