Technique selection hinges on volatility/polarity; LC‑HRMS typically initiates characterization for nonvolatile/semi-volatile features, while GC‑MS can resolve ...

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 ...

Ambient ionization via rapid evaporative ionization MS provided near-real-time lipid fingerprints, complementing hyphenated ...

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

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 ...

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 ...

Eliminating solid supports reduces clogging, stationary-phase degradation, and irreversible binding, improving recovery for “sticky” or overload-prone analytes and extending robustness with complex ...

Sheher Mohsin and Jeremy Koemel explore where machine learning and predictive CCS could transform PFAS identification, and what's holding it back. Sheher Mohsin and Jeremy Koemel identify the biggest ...

Sheher Mohsin explains how CCS measurements add a physical confirmation layer beyond mass and retention time in PFAS analysis. Why are ion mobility and CCS measurements becoming increasingly important ...

A controlled-degradation/RPLC–HRMS pipeline enables sequence-level PLGA microstructural readouts by converting >100 kDa polymers into <~1–2 kDa oligomers suitable ...

EGCG, or epigallocatechin gallate, is a high-value green tea polyphenol with strong relevance in nutraceutical, botanical, and natural product research. This application note presents a liquid-liquid ...
