He describes how labs often receive samples with vague instructions to simply "find out what PFAS are in it," when what's ...
Bryan Vining notes that early PFAS concern centered on eight-carbon compounds like perfluorooctanoic acid (PFOA) and ...
Shimadzu expanded its eTOC portfolio with the TOC-1000e S to continuously quantify trace organic contamination in ultrapure ...
Ambient ionization via rapid evaporative ionization MS provided near-real-time lipid fingerprints, complementing hyphenated ...
Sensor gas chromatography (GC) determines whether water chasers change alcohol metabolism. Hangovers can make it harder to safely drive a car or work in jobs that require careful attention, on top of ...
This week, Chromatography Online spoke with Yifan Liu (Northeastern University) about her ASMS 2026 talk on low-temperature HILIC, showing how dropping the operating temperature c ...
Jie Du of Cardinal Health discusses with LCGC International how switching from reversed-phase to hydrophilic interaction liquid chromatography (HILIC) can unmask a hidden excipient artifact mistaken ...
Bryan Vining introduces one of the most persistent problems in per- and polyfluoroalkyl substances (PFAS) work: background contamination. Because PFAS compounds are so ubiquitous, he notes, measuring ...
uMRM links untargeted MS/MS acquisition to quantitative workflows, prioritizing experimentally derived fragmentation over purely in silico predictions. Empirical controls and noise-filtering ...
Method harmonization takes center stage as moderator Bryan Vining opens a discussion on one of per- and polyfluoroalkyl substances (PFAS) analysis's thorniest problems: too many compounds, and too ...
Technique selection hinges on volatility/polarity; LC‑HRMS typically initiates characterization for nonvolatile/semi-volatile features, while GC‑MS can resolve ...
