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.

Heating can autonomously increase fingermark contrast on 304 stainless steel, as shown by direct in-situ observation of ridge ...

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 ...

LCGC International spoke to the University of Salerno’s Eduardo Maria Sommella and Danila La Gioia regarding a new hydrophilic interaction liquid chromatography-high resolution mass spectrometry ...

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 ...
