Mass spectrometry imaging using an ambient ionisation technique has been used to map a recently discovered phenylethylamine novel psychoactive substance (NPS) in blotter paper where GC/MS failed to detect it.

The technical challenges and strategies of LC/MS-based quantification and characterization of biotherapeutics have been reviewed, with emphasis on the analysis of antibody-based biotherapeutics such as monoclonal antibodies and antibody-drug conjugates.

The adulteration of roasted coffee beans with coffee husks, corn or soybean has been detected using capillary electrophoresis-mass spectrometry to measure the monosaccharides originating from the constituent polysaccharides present in the beans.

For over 20 years, each issue of the Journal of Mass Spectrometry has contained a Special Feature article. These are highly regarded in the mass spectrometry community and extremely popular with researchers around the globe. These features are freely available to the entire mass spec community.

Selected key technologies of the analytical science industry are discussed by Steve Down with reference to burgeoning application areas and the scope for future improvements.

Ion source pressure plays a significant role in the process of ionization and the subsequent ion transmission inside a mass spectrometer. Pressurizing the ion source to a gas pressure greater than atmospheric pressure is a relatively new approach that aims to further improve the performance of atmospheric pressure ionization sources. A brief review on the development of super-atmospheric pressure ion sources, including high-pressure electrospray, field desorption and superheated ESI, and the strategies to...
