The application of ICP-MS for the characterization of single nanoparticles in biological and environmental water samples

The rapidly growing use of engineered nanomaterials in many environmentally relevant applications requires novel analytical approaches for determining their presence and concentrations in water and other environmental matrices. To date there are no standard methods for monitoring this emerging class of materials. Advances in ICP-MS software and hardware, available in the Agilent 7900, allow the detection of single nanoparticles in these environmental matrices. The webinar will present an application of...

Elemental information may not be enough to protect customer’s health. In fact, element chemical form is the most important parameter in compound toxicity or physiological effects. New food regulations require speciation analysis to guarantee food safety. Combination of Shimadzu’s ICPMS-2030 and LC20-Ai is a valuable solution to solve this new challenge.

Current findings and the future role of functional MRI modalities for studying the treatment effects of various medications on Alzheimer's disease and mild cognitive impairment have been reviewed, focusing on medications that have been approved by FDA rather than new drugs undergoing trials.

This review focuses on exosome isolation and purification methods and their implications in HIV‐1 studies as well as the roles of proteomic techniques in defining exosomal contents and the research and clinical applications of proteomics and exosome in HIV‐1 biology.

A comparison of four commonly used proteomics sample preparation methods for head and neck tissues has revealed that there is no universal method, each having their own deficiencies and advantages.

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...
