New Findings Shed Light on Formation and Analysis of Doubly Charged Lipid-Metal Ion Complexes
June 30th 2023Researchers have discovered that phospholipids form doubly charged lipid-metal ion complexes during electrospray ionization (ESI), providing valuable insights into the analysis of phospholipid structures.
New Method Enables Accurate Analysis of Aminoglycoside Antibiotic Residues in Aquatic Products
June 30th 2023Researchers have developed an ultrahigh-pressure liquid chromatography (UHPLC)—tandem mass spectrometry (MS/MS) method for the simultaneous determination of 10 aminoglycoside antibiotics in aquatic products.
New LC–MS/MS Data Analysis Framework, MCnebula, Streamlines Untargeted Analysis
June 29th 2023Researchers have introduced MCnebula, a new framework for untargeted LC–MS/MS data analysis. MCnebula focuses on critical chemical classes and utilizes visualization techniques to streamline the analysis process, enabling efficient pathway analysis, biomarker discovery, and classification of unknown compounds beyond the limits of spectral libraries.
New Method Enables Analysis of Polycyclic Aromatic Hydrocarbons in Plastics Production Intermediates
June 29th 2023A new method has been developed for detecting and quantifying polycyclic aromatic hydrocarbons (PAHs) in intermediates used in plastics production. The method, based on liquid chromatography column switching, allows for the analysis of 18 PAHs and addresses the lack of regulatory oversight for PAH concentrations in plastic intermediates.
