What's going on in Dresden?
Monday’s afternoon sessions will kick off with David McCalley, Karl-Siegfried Boos and Stephan Lamotte, as well as D. Belder delivering parallel troubleshooting tutorials on how to obtain good peak shapes and efficiencies when using reversed phase and hydrophilic interaction separations, how to overcome problems in bioanalytical LC–MS–MS and how to overcome obstacles related to the miniaturization of separation processes respectively.
Heinz Engelhart, Karl-Siegfried Boos and Frank Steiner then chair parallel sessions on the work of Barry Karger, Clinical Analysis and a second series of lectures on Fundamental Aspects of HPLC.
Highlights of the Barry Karger sessions include Wolfgang Lindner on the hope (or hype) attached to HILIC-type selectivities, Frantisek Foret on the potential of nanotechnology in bioanalysis and Andras Guttman on new developments in fluorescent isotope coded affinity tag (FCAT) labelling of tryptic peptides. Wolfgang Gotzinger closes the event with his findings on achiral purification of small molecules by SFC and role of MS-directed purification.
Topics in the Clinical Analysis session include selective ESI-MS pre-column derivitization reagents for screening aldehyde biomarkers by Hubertus Irth, Molarino on assessing renal function for potential kidney donation using iothalamate quantification using UPLC–MS–MS, Ron Majors on trends in sample prep and Rosa Morello on in-line processing of whole blood using SPE-LC–MS–MS.
The second part of the Fundamental Aspects series kicks off with Gert Desmet critically appraising Giddings and general rate plate height models, Torgny Fornsted on accurate in-depth characterization of analytical and preparative phase systems, Kanji Miyabe will discuss a numerical method to analyse tailing peak profiles and A. de Villiers will discuss the effect of analyte properties on the kinetic performance of LC separations.
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.
PFAS Analysis in Practice: A RAFA 2024 Interview with Stefan van Leuwen
January 10th 2025At the Recent Advances in Food Analysis (RAFA) conference in 2024, LCGC International sat down with Stefan van Leuwen of Wageningen Food Safety Research to discuss his research, which addresses emerging challenges in circular food production, focusing on the risks posed by pollutants when waste and by-products are repurposed in food systems.
