Session 430, Room 311C
An innovative oral session called Liquid Chromatography: Stationary Phase Architecture chaired by Richard A. Henry from Supleco/Sigma Aldrich (Bellefonte, Pennsylvania) begins at 8:00 a.m. today in Room 311C.
The discussion kicks off with an interesting presentation on the Characterization of Carbon-modified Silicas for Analytical Liquid Chromatography by Stephen R .Groskreutz from Gustavaus Adolphus College (St. Peter, Minnesota) followed by a talk on Using Solvent Particle Interactions to Predict Slurry Packing and Performance of 1.2 µm Superficially Porous Particles Packed in Capillary Columns for Liquid Chromatography by Laura Blue from the University of North Carolina (Chapel Hill, North Carolina).
A research project on the Performance Reproducibility of Chromatographic Columns Packed With Sub-3 µm Core-Shell Particles is described by Fabrice Gritti from the University of Tennessee-Knoxville (Knoxville, Tennessee). Richard A. Henry will then discuss the Equivalency of Selectivity Plots for Porous and Superficially Porous Particles.
A short interval in the proceedings is followed by a lecture by Chuan-Hsi Hung from Brigham Young University (Provo, Utah) on the Comparison of Efficiencies of Diamond-based Core-Shell Materials for HPLC Made with Different Sizes of Nano-diamonds and Core Carbon Particles.
1.2 µm Large Pore, Thin-shell Superficially Porous Particles and their Chromatographic Performance in Capillary LC Columns is described by James W, Treadway from the University of North Carolina at Chapel Hill (Chapel Hill, North Carolina) followed by a talk on the Evaluation of 2 µm Nonporous Organolsilica Hybrid Particles for LC by Amber Moore from SUNY at Buffalo (Buffalo, New York).
The session closes with a presentation by Xiaddong Liu from Thermo Fisher Scientific (Sunnyvale. California) on High Performance Speciality Columns for Surfactant Analysis.
Detecting Hyper-Fast Chromatographic Peaks Using Ion Mobility Spectrometry
May 6th 2025Ion mobility spectrometers can detect trace compounds quickly, though they can face various issues with detecting certain peaks. University of Hannover scientists created a new system for resolving hyper-fast gas chromatography (GC) peaks.
University of Oklahoma and UC Davis Researchers Probe Lipidomic Profiles with RP-LC–HRMS/MS
May 6th 2025A joint study between the University of Oklahoma Health Sciences Center (Oklahoma City, Oklahoma) and the UC Davis West Coast Metabolomics Center (Davis, California) identified differentially regulated lipids in type 2 diabetes (T2D) and obesity through the application of reversed-phase liquid chromatography-accurate mass tandem mass spectrometry (RP-LC-accurate MS/MS).
Automated Sample Preparation (ISO 20122) for MOSH/MOAH in Seasoning Oils
May 6th 2025This work presents an Automated Sample Preparation procedure for MOSH/MOAH analysis of Seasoning Oils. We compare results from a manual epoxidation procedure compliant with DIN 16995 with results based on fully automated sample preparation (epoxidation and saponification) compliant with ISO 20122. In both cases, online clean-up via activated aluminum oxide (AlOx) are used to remove interfering n-alkanes from the MOSH fraction during the HPLC run. Automated data evaluation using a dedicated software (GERSTEL ChroMOH) is presented.
