Bruker's XFlash® 7 EDS detectors, with a large solid angle and high performance pulse processing, enable fast live chemical mapping using ESPRIT LiveMap with output count rates up to 1000 kcps.

ESPRIT LiveMap can be used for a multitude of applications where ROI identification is necessary, for example for the location of intermetallics, contamination, interface regions, trace elements, etc. Features such as automatic identification of elements and online deconvolution of overlapping peaks are integrated in ESPRIT LiveMap.

This example shows live EDS chemical mapping of Al-Si alloy with a transient liquid phase (TLP) bonded Sn-Cu interlayer or brazing seam. The complex distribution of the microstructure of different layers can be seen. The top layer is the Al-Si alloy and the bottom is the Sn-Cu brazing seam region. Cr contamination was automatically identified and added to the map data. This example demonstrates how ESPRIT LiveMap can be used to locate contamination in the Cu-Sn brazing seam.

ESPRIT LiveMap 主要特征:

  • Live chemical mapping with high output count rate of up to 1000 kcps
  • 自动标定样品表面所含元素
  • Spectrum extraction of localized features using mapping objects
  • Live identification of trace elements (single pixel enrichment)
  • Live update of detected elements (manual or automatic)
  • User defined resolution for ESPRIT LiveMap and easy switch to conventional mapping
