Within the manufacturing process of bio-therapeutics, quality control (QC) plays a fundamental role in guaranteeing the supply of a high quality product. Any changes in the product formulation or degradation can affect the therapeutic role, leading to a potential loss of activity or development of toxicity. Amongst the several analytical techniques that can be used to determine the quality of a synthetic bio-product, MALDI-TOF mass spectrometry is widely employed due to its rapid and simple operation, low...

The most precise measurement of the radius of the proton from electron-scattering experiments is in agreement with recent muonic atomic spectroscopy results and shrinks the sub-atomic particle from 0.88 femtometres to 0.831 fm.

A new model could help chemists work out the optimum conditions for reduce carbon dioxide to more industrially useful substances, such as formaldehyde.

X-ray crystallography undertaken at the Canadian Light Source in Saskatchewan, and the Advanced Photon Source in Illinois, USA, have given scientists an ultra-high resolution three-dimensional structure of non-ribosomal peptide synthetases, NRPS enzymes, The work could lead to new therapeutic approaches to treating bacterial infection.

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...
