Tuesday Morning Session on Chiral Separations
Terry Berger of Berger Instruments (Newark, Delaware) and Geoffrey Cox of Chiral Technologies, Inc. (West Chester, Pennsylvania) will chair a Monday morning session titled "Chiral Separations" in Ballroom B.
Terry Berger of Berger Instruments (Newark, Delaware) and Geoffrey Cox of Chiral Technologies, Inc. (West Chester, Pennsylvania) will chair a Monday morning session titled “Chiral Separations” in Ballroom B.
The session’s first presentation will be given by Wolfgang Lindner of the University of Vienna (Vienna, Austria). The title of Linder’s presentation is “The Potential of Novel Zwitterionic Chiral Ion Exchanger for HPLC Enantiomer Separations of Charged Analytes.”
Lindner’s presentation will be followed by a study presented by Kenji Hamase of Kyushu University (Fukuoka, Japan). Hamase’s presentation is titled “Two-Dimensional HPLC Determination of All Proteinogenic Amino Acid Enantiomers in Mammalian Tissues and Physiological Fluids.”
The final talk in this Monday session is titled “Chiral Gradient Elution Separations: Modeling of Normal and Reversed-Phase Systems and Prediction of Resolution for Complex Mixtures.” It will be presented by Session Co-Chair Geoffrey B. Cox.
Following Cox’s presentation, attendees are invited to Exhibit Hall A&B for a light breakfast and snacks.
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.
Metabolomics Analysis of Low Birth-Weight Infants Using UHPLC-MS/MS Following Lipid Emulsion
January 10th 2025A recent study aimed to directly compare the changes in serum metabolites among very low birth-rate (VLBW) infants following the administration of the soybean oil-based lipid emulsion and soybean oil, medium-chain triglycerides, olive oil, and fish oil (SMOF) lipid emulsion using untargeted metabolomics techniques.
Analyzing New Drug Modalities: An ISC 2024 Interview with Kelly Zhang
January 10th 2025At ISC 2024 in Liverpool, United Kingdom, LCGC International interviewed Kelly Zhang of Genentech about her work analyzing new drug modalities, such as mRNA, oligonucleotides, peptides, and cell and gene therapies.
