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 ...

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 ...

Nikoline Juul Nielsen from the University of Copenhagen, Denmark explores deprotomer formation for accurate CCS prediction and metabolite identification and the potential of implementing these ...

Wallman unpacks how graph-level fragmentation in fragDETR captures internal fragments and neutral losses, with peak and intensity improvements concentrated in challenging non-standard peptides. Georg ...

Wallman explains how spectral library accuracy, retention time prediction, and instrument-specific variation make deep learning essential yet difficult in data-independent acquisition proteomics.

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

Sugar accumulation and organic-acid depletion during ripening jointly determine potential alcohol, perceived sweetness, pH, color stability, and spoilage risk, making their ratio a practical ...
