EDAX Octane Elite EDS System for Energy Dispersive Spectroscopy (EDS/EDX) Analysis

The EDAX Octane Elite EDS system, equipped with Octane Elite silicon drift detectors (SDDs), represents a significant leap in energy dispersive X-ray spectroscopy (EDS/EDX) analysis.

This EDAX system features detectors with a silicon nitride (Si₃N₄) window, resulting in remarkable enhancements in low-energy sensitivity for microanalysis at low kV and the detection of light elements.

Furthermore, the Octane Elite detectors utilize technology that enables high-speed X-ray data processing within a compact, fully vacuum-encapsulated detector device.

Octane Elite silicon drift detectors

The Octane Elite SDDs are built with a silicon nitride (Si₃N₄) window, a motorized slide, and high-speed electronics. They can seamlessly integrate with EDAX's electron backscatter diffraction (EBSD) cameras and/or wavelength dispersive spectroscopy (WDS) detectors, forming either the Trident (EDS-EBSD-WDS) system or the Pegasus (EDS-EBSD) system. These combinations provide comprehensive solutions for materials characterization.

There are two models of the Octane Elite SDDs:

Octane Elite Plus - 30 mm² chip

Octane Elite Super - 70 mm² chip

Best light element performance

In comparison to a polymer window, the silicon nitride window offers significant improvements, resulting in greatly enhanced performance when it comes to detecting light elements and delivering considerably more essential data for the analyst.

Si₃N₄ window

The silicon nitride window offers excellent low-energy transmission, surpassing the performance of a polymer window.
