Bryan Vining notes that early PFAS concern centered on eight-carbon compounds like perfluorooctanoic acid (PFOA) and ...

He describes how labs often receive samples with vague instructions to simply "find out what PFAS are in it," when what's ...

Shimadzu expanded its eTOC portfolio with the TOC-1000e S to continuously quantify trace organic contamination in ultrapure ...

LC-MS/MS identified chlortetracycline in 1/29 and doxycycline in 4/29 chicken-based cat kibbles, indicating sporadic antibiotic carryover into finished commercial diets. PFAS were detected in 7/29 ...

Cardinal Health discusses with LCGC International how switching from reversed-phase to hydrophilic interaction liquid chromatography (HILIC) can unmask a hidden excipient artifact mistaken for a true ...

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 ...

The workshop will cover multidimensional gas and liquid chromatography trends, featuring keynote speakers from academia and industry. Participants can engage in guided discussions, poster sessions, ...

Vladimir Shulaev | Author | LCGC International provides separation science insights, including liquid chromatography (HPLC), gas chromatography (GC), and mass spectrometry (MS).

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 ...
