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 ...

A sequential, stage-specific sampling strategy was paired with GC–MS, electronic nose, HPLC, and GC to quantify evolving aroma compounds and flavor precursors. Seventy-two aroma-active compounds were ...

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 ...

Gary Siuzdak explains how uMRM converts inconsistent untargeted LC–MS data into standardized MRM transitions. Join the global community of analytical scientists who trust LCGC for insights on the ...

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 ...
