GPC/SEC analysis of Mono-, Di-, Tri-acylglyceride's
Polymer Standards Service-USA Inc. has published an Application Note on GPC/SEC analysis of Mono-, Di-, Tri-acylglyceride's and Glycerol according to European Pharmacopoeia. A PSS SECcurity GPC1200 System with refractive index detector was used in this analysis. The use of a single PSS SDV gel, 5?m, 100?, 8x600 mm GPC column aids in maximizing separation efficiencies. The use of PSS WInGPC Unity software for data collection and processing allows for rapid analysis and reporting. Polymer Standards Service-USA Inc. Warwick, Rhode Island.
A Novel LC–QTOF-MS DIA Method for Pesticide Quantification and Screening in Agricultural Waters
May 8th 2025Scientists from the University of Santiago de Compostela developed a liquid chromatography quadrupole time-of-flight mass spectrometry (LC–QTOF-MS) operated in data-independent acquisition (DIA) mode for pesticide quantification in agriculturally impacted waters.
Distinguishing Alcohol- from Non-Alcohol-Associated Liver Cirrhosis with LC-MS
May 7th 2025A pilot study investigating whether nicotinamide adenine dinucleotide kinase (NADK) expression is selectively diminished in alcohol-associated liver cirrhosis (AC), as well as evaluating its potential as a biomarker for this condition, measured AC and non-AC (NAC). Nicotinamide adenine dinucleotide (NAD+) and nicotinamide adenine dinucleotide phosphate (NADP+) levels in human liver samples were measured using liquid chromatography-mass spectrometry (LC-MS).
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).
