EDS analysis of Au-WS2 core–shell nanoparticles
January 30, 2026

EDAX Octane Elite Ultra is the revolutionary energy dispersive x-ray spectroscopy (EDS/EDX) system for compositional analysis in the scanning electron microscope (SEM). The Octane Elite Ultra establishes a new benchmark for EDS systems utilizing a newly developed proprietary windowless 160 mm2 EDS detector. This not only delivers superior sensitivity to light and heavy elements but provides accurate analytical results at accelerating voltages up to 30 kV, making the Octane Elite Ultra the first windowless EDS detector suitable for everyday use. This unrivaled performance eliminates the need for a secondary EDS detector and ensures that your most demanding application needs are now met.
