Getting the Most for the Effort...Quickly

In this article, the use of comprehensive two-dimensional liquid chromatography (LC×LC) coupled to mass spectrometry (MS) for characterizing glycosylation of therapeutic enzymes is presented.

How is mD-LC–MS changing the way we evaluate HPLC peaks and assess performance?

In the first LCGC Blog of 2025, Caitlin Cain of the University of Michigan highlights the divide between gas and liquid chromatographers, and why both types of techniques should be in the same conversations.

LCGC International sat down with Jose Bernal to discuss his latest research in using pyrolysis gas chromatography–mass spectrometry (Py-GC–MS) and other chromatographic techniques in studying microplastics in food analysis.

In this column, we discuss the label-free and stable isotope labeling proteomics approaches that help in biomarker discovery. We also discuss the different enrichment techniques, such as stable isotope labeling by amino acid in cell culture (SILAC), isobaric tags for relative and absolute quantitation (iTRAQ), and tandem mass tags (TMT, that help in measuring low-abundance protein biomarkers.

Known as “forever chemicals”, PFAS exposure has been linked indirectly and directly to a range of potential health issues. The objective of this study was the development of an optimized sample preparation and LC–MS/MS method for the analysis of PFAS in serum for biomonitoring applications.
