Yelena Sapozhnikova from the United States Department of Agriculture spoke to The Column about her innovative research investigating PFAS in plastic food storage bags using targeted and non-targeted liquid chromatography–tandem mass spectrometry.
Breakthrough Method Enables Discovery of Natural Aldehydes for Metabolomics Research
June 14th 2023The development of a newly-designed Girard's reagent, HBP, as charged isobaric mass tags has enabled selective capture and sensitive detection of aldehyde metabolites. The LC–dNLS-MS/MS screening approach using this reagent has successfully facilitated the discovery of natural aldehydes and their profiling in complex samples.
Adjustable Polyacrylamide Stationary Phases Enhance Separation Performance in Liquid Chromatography
June 12th 2023Adjustable polyacrylamide stationary phases developed by researchers enhance separation performance in liquid chromatography, according to a recent publication. The study demonstrates the synthesis of vinyl modified silica and the successful preparation of polyacrylamide modified silica (PAM-SIL) stationary phases, allowing for fine control of separation performance.
LC–MS Methods Evaluate PFAS and Lipidomic Changes of Lettuce and Peanuts in Contaminated Soil
June 6th 2023In a talk at ASMS 2023, Rebecca L. Beres of the University of North Carolina at Chapel Hill focused on two types of analysis methods: liquid chromatography coupled to tandem mass spectrometry (LC–MS/MS) and a liquid chromatography, ion mobility spectrometry, and mass spectrometry (LC–IMS-MS) platform.
A Standardized 2D-LC Screening Platform for Peak Purity Determination in Pharmaceutical Analysis
June 1st 2023This study suggests a 2D-LC screening method to evaluate peak purity and ensure specificity in pharmaceutical analysis, thereby promoting the safe production of medicines by detecting active pharmaceutical ingredients (API) and related substances.
