Michael Dong recently discussed sample preparation (SP) techniques for small-molecule drug substances and solid dosage forms.

Michael Lämmerhofer from the Institute of Pharmaceutical Sciences, University of Tübingen, Germany, spoke to JFK Huber Lecture Award winner of 2024 Torgny Fornstedt, professor in analytical chemistry and leader of the Fundamental Separation Science Group, Karlstad University, Sweden, about his pioneering work in high performance liquid chromatography (HPLC) with a focus on fundamentals and industrial applications.

In this month's edition of LC Troubleshooting, Dwight Stoll and his fellow researchers discuss both the benefits (improved peak shape/loading) and challenges (excessive interaction) associated with charge-doped reversed-phase (RP) columns for both analytical and preparative separations.

A study conducted by the Agriculture Research Centre of Giza, Egypt, and Jilin Agricultural University in China, evaluated the efficacy of stinging nettle extract, nettle smoke, and formic acid in the controlling of Varroa mites, a major threat to honeybee colonies, with a focus on mite infestation reduction, honeybee mortality, and biochemical responses. Gas chromatography–mass spectrometry (GC–MS) was used to identify key bioactive compounds in the stinging nettle extract.
