Optimizing sample preparation is critical for generating high-quality, reproducible analytical data, particularly when working with complex matrices. Yet, it often demands significant time and effort.

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 ...

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 ...

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 ...

Melissa Dunkle, senior research scientist at Dow Benelux BV, The Netherlands, explores practical aspects of using multidimensional pyrolysis gas chromatography (Pyr-GCxGC) to investigate fluoropolymer ...

Sample preparation takes the spotlight as the panel debates the trade-offs between direct injection and solid-phase extraction (SPE). David Megson recalls trace-level analysis in complex matrices from ...
