Researchers Retract Error in MS Paper
A correction will be published in Angewandte Chemie for the MS paper presented by Fredric Menger at Emory University in Atlanta.
A correction will be published in Angewandte Chemie for the MS paper presented by Fredric Menger at Emory University in Atlanta. "Our MS mass was twice that of the monomer because, apparently, dimers form in the gas phase of the mass spectrometer, a point that we did not realize at the time," says Menger. He adds there is much in his paper that is correct and useful; the theoretical work on the structure of 12-membered annulene is still valid and the compounds he made are still useful surfactants.

December 20th 2024This 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.
Using LC-MS/MS to Measure Testosterone in Dried Blood Spots
December 19th 2024Testosterone measurements are typically performed using serum or plasma, but this presents several logistical challenges, especially for sample collection, storage, and transport. In a recently published article, Yehudah Gruenstein of the University of Miami explored key insights gained from dried blood spot assay validation for testosterone measurement.
