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...

Optimize Laboratory Productivity through System Utilization Monitoring and Business Analytics

System utilization is often recognized as the key to unlocking operational insights for effective laboratory productivity. However, the definitions of system utilization can vary greatly and can have dramatically different use models. Join us to discover the many ways to look at and interpret utilization data as well as other asset management data to build a complete picture of your lab. In this webinar, we will cover the multiple sources of utilization data, review the benefits and limitations of each...

The amount and types of triglycerides (fats and oils) in the diet are linked to a number of disease conditions, but current methods of determining the exact position of the fatty acids on the glycerol portion of these compounds are slow and cumbersome. Scientists from the University of Massachusetts Boston have devised a new method employing mass spectrometry to distinguish between the different positional isomers of triglycerides.

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...
