A Question of Time (and Date)

This collection of technical articles, interviews, and news pieces delves into the latest innovations in LC methods, including advance in high performance liquid chromatography (HPLC), ultrahigh-pressure liquid chromatography (UHPLC), liquid chromatography–mass spectrometry (LC–MS), and multidimensional LC.

In this LCGC International interview with Beatrice Campanella from the Institute of Chemistry of Organometallic Compounds (ICCOM) in Pisa, Italy, which is part of the Italian National Research Council (CNR), we discuss her recent research work published in Food Chemistry on the subject of a method for quantifying methionine and selenomethionine in food matrices using gas chromatography–mass spectrometry (GC–MS) with aqueous derivatization by triethyloxonium salts (1).

In this article, we review some key considerations for chromatographic technique selection and method development across the full drug process—from early-stage active pharmaceutical ingredient (API) synthesis to routine commercial release activities.

Separation scientists frequently encounter critical pairs that are difficult to separate in a complex mixture. To save time and expensive solvents, an effective alternative to conventional screening protocols or mathematical peak width reduction is called iterative curve fitting.

In this installment of "LC Troubleshooting," Dwight Stoll discusses several essential principles related to when and why buffers are important, as well as practical factors, such as commonly used buffering agents, that are recommended for use with different types of detectors.
