An LC–HRMS approach for the simultaneous analysis of 15 N-nitrosamines in multiple APIs using a novel HILIC-based SPE clean-up step has been developed and tested.

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).

Here is some of the most popular content posted on LCGC International this week.

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.
