Analysis of Linear and Branched Polyethylene Glycols via GPC Viscometry
Biomedical interest in branched type PEG materials has increased due to their lower viscosity in comparison with equivalent linear type polymers. Investigation of PEGs by GPC can be used to elucidate their relatively compact nature in solution.
LC–MS/MS-Based System Used to Profile Ceramide Reactions to Diseases
April 26th 2024Scientists from the University of Córdoba in Córdoba, Spain recently used liquid chromatography–tandem mass spectrometry (LC–MS/MS) to comprehensively profile human ceramides to determine their reactions to diseases.
High-Throughput 4D TIMS Method Accelerates Lipidomics Analysis
April 25th 2024Ultrahigh-pressure liquid chromatography coupled to high-resolution mass spectrometry (UHPLC-HRMS) had been previously proposed for untargeted lipidomics analysis, but this updated approach was reported by the authors to reduce run time to 4 min.
