Mass Spectrometry

A systematic approach to method improvement can save time and resources by using methods that are likely to be better, and more robust, than those developed using a trial-and-error approach.

Some traditional MAM workflows are being substituted with iMAM workflows that rely on analyzing the intact mass of mAbs in their native form, resulting in significant improvements in high-throughput sample analysis.

A novel LC–MS/MS method, with a dual ESI and APCI source using simple solvent extraction for sample preparation, was validated for analysis of 102 pesticides and 5 mycotoxins regulated by Colorado state in dried hemp.

The monitoring of per- and polyfluoroalkyl substances (PFAS) into food is an important environmental and health concern. Raquel Sendón García, PhD, is a Faculty Member in the Department of Analytical Chemistry of Nutrition and Food Science, and a Faculty of Pharmacy member at the University of Santiago de Compostela in Spain. She has been performing research on food contamination and the presence of potentially harmful chemicals in foods for some time. We recently spoke to her about her work using GC–MS and other analytical techniques to analyze PFAS migration into food from packaging materials.
