Thanks to their combination of high-resolution electron optics and wavelength dispersive x-ray spectroscopy, JEOL electron probe microanalyzers deliver a highly sensitive, spatially resolved (trace) element analysis with very high reproducibility.
Li batteries are used in mobile phones or vehicles, among other things. Thanks to the newly developed light element spectrometer from JEOL, detecting in a microscope has for the first time become routine and standard with high spatial resolution and detection sensitivity.

The detection of rare earths is not only of interest for mineralogical samples, it is also becoming increasingly significant due to the continuous development of high-performance microelectronics. For decades, JEOL has been setting the bar for detecting the mostly low-concentrated elements with its energetically and spatially high-resolution trace element analytics.

Minerals are frequently complex structures formed from a multitude of elements. Element mapping images are one of the most important methods for achieving the spatially resolved visualisation of the chemical composition. These mapping images can be used to gather essential information on e.g. the creation and structure of the samples under examination. For this task, JEOL supplies the most stable and most energetically and spatially high-resolution spectroscopy systems.

High-resolution element maps are of central significance for understanding geological processes. Over many decades, JEOL electron probe microanalyzers have proven to be the perfect tool for the reliable, automated examination of diffusion profiles and the spatial distribution of trace elements. Our detection threshold for this non-destructive method is less than 20 ppm.
