In chromatographic analysis, the number of repeated measurements is often limited due to time, cost, and sample availability constraints. It is therefore not uncommon for chromatographers to do a single measurement.

Protecting your network chromatography data system (CDS) data is critical and a service level agreement (SLA) with your IT provider is vital. What should be included? Are SLAs for in-house IT and SaaS (software as a service) similar?

LCGC International spoke to Lauren Lovejoy, principal scientist in the Drug Substance and Product Analysis group at GSK (Philadelphia, Pennsylvania), about the advantages of using tandem columns in sequential elution liquid chromatography (SE-LC) to investigate weak acids, neutral compounds, and permanent anions in pharmaceutical applications.

In this installment, we will review the fundamental terminology and data analysis principles in benchtop GC–MS. We will compare the three modes of analysis—full scan, extracted ion chromatograms, and selected ion monitoring—and see how each is used for quantitative and quantitative analysis.

In this installment of “LC Troubleshooting,” Dwight Stoll touches on highlights from Pittcon 2025 talks, as well as troubleshooting advice distilled from a lifetime of work in separation science by LCGC Award winner Christopher Pohl.

Scientists from the Zhejiang Institute of Quality Scientists used liquid chromatography–tandem mass spectrometry to detect 35 PFAS in paper and plastic products.

A recent study used a liquid chromatography-drift tube ion mobility spectrometry-high resolution mass spectrometry (LC-DTIMS-HRMS) platform to contribute to characterizations of 175 per-and polyfluoroalkyl substances (PFAS) with authentic standards in a multidimensional manner.

A new study from the University of Tübingen presents a new Python-based open-source software tool for PFAS detection.
