New! Windowless high collection angle EDS detector with 100 mm² oval silicon drift detector area

On-Demand Session - 52 Minutes

New Energy-dispersive X-ray Spectrometer

We announce the release of a new large collection angle EDS detector with an oval shaped SDD area of 100 mm2, the XFlash® 6T-100 oval for TEM and STEM and the XFlash® 6-100 oval for SEM and T-SEM.

This webinar will inform about the detector features, specifics of microscope detector geometries as well as respective data acquisition and analysis. Qualitative and quantitative element mapping for different large collection angle EDS settings will be explained (Fig. 1, 2) and related to results obtained by standard EDS.

The detector has been shown to provide collection angles between 0.4 sr to 0.7 sr at high take-off angles of around 12° on TEM/STEM and collection angles of up to 0.4 sr on SEM. The pole piece to detector geometry is optimized for each specific microscope type in cooperation with the microscope manufacturer. This enables fast and routine element mapping at the nanometer scale without compromising the microscope performance, suitable electron probe quality and specimen preparation provided. In STEM atom column EDS (Fig. 3, [1]) as well as single atom identification [2] become possible.
