Presentations
An introduction to Orbitraps and their capabilities A novel mass analyzer that offers resolutions up to (FWHM) of 120-480k depending on the model, with mass accuracy better than +/- 1ppm. These high-resolution accurate-mass systems can detect a wide range of compounds and small molecules during both targeted and untargeted analyses. |
Small molecule LC/MS applications with Orbitrap systems Examples will be shown with customer data in multiple application markets, centered around screening various matrices for compounds of interest. |
The future of isotope ratio mass spectrometry The direct isotope ratio analysis of intact polar molecules is made possible using electrospray ionization Orbitrap technology. This transformative analytical technique provides a wide range of isotopic information from singly and mulitply substituted isotopologues, mass independent fractionation, and position specific isotope analysis of organic molecules. We demonstrate sub-‰ precision and accuracy when analyzing various different oxy-anion compounds, and present the latest results and discoveries of this new development. |
New applications for isotopes in life science Isotopic analysis of biological samples providing new biomarkers for the monitoring and diagnosis of diseases. |
Thermo Scientific Neoma MS/MS: the future of MC-ICP-MS The Neoma is the next generation MC-ICP-MS from Thermo Fisher Scientific with full MS/MS capabilities. Accurate, high-precision isotope ratio measurements are possible for the first time with an ICP-MS/MS system, and the Neoma achieves this without sacrificing sensitivity, stability, or exponential mass fractionation. We present exciting new results of in-situ 87Rb-87Sr analyses of terrestrial and extraterrestrial materials. |
