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).
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.
