A joint study conducted by the University of Copenhagen, the Technical University of Denmark, and the University of Cambridge explored a potential untapped archive from natural history collections (particularly specimens relating to historical beeswax) using liquid-chromatography-tandem mass spectrometry (LC-MS/MS) to examine a honeybee queen cell specimen from the 19th century.

In early 2025, major U.S. science agencies faced deep budget reductions under the new Department of Government Efficiency (DOGE), disrupting research funding, delaying projects, and creating widespread uncertainty.

A joint study conducted by the University of Guelph, the University of Illinois, and Champion Petfoods Holdings used high performance liquid chromatography (HPLC) in their analysis of the polyphenol profile in cat and dog kibble with blueberries listed on the ingredient deck.

In recent years, analytical chemists have increasingly adopted a sustainability viewpoint. Yet, at the same time, they still use traditional organic solvents for extractions and other procedures. In this installment of Sample Preparation Perspectives, we will look at solvent selection from green considerations. Trends on solvent use are presented, followed by a discussion on what makes a green solvent. Finally, the CHEM21 Solvent Selection Guide is examined as representative of tools for selecting green solvents for use in analytical methods and other chemical processes.
