EDS Mapping


  • Counts per second (CPS) map showing count rate quality at every pixel displayed to provide a CPS distribution and highlights variations caused by surface features
  • CompoMaps separate contributions from overlapping peaks to individual elemental maps for more accurate representations of EDS maps
  • Quickly activate and add elements while mapping to simplify operation and inspection
  • Select from 40 color options to effortlessly create vibrant images during elemental mapping
  • Simultaneously map multiple element lines (K, L, M)
Dynamic Element Mapping


  • Interact in real-time to show only the elements while in Mapping and Linescan modes
  • Edit elements, element lines, and user-selected regions of interest during map collection

Montage Large Area Mapping


  • Scan large areas using stage movements to collect multiple fields of analysis
  • Automatically stitch data into a single file for comprehensive analysis
Smart Phase Mapping


  • No user setup required
  • Automatically collect spectra, elemental, and phase maps
  • Customize the name and color selection of phases
  • Predefine or reanalyze phases based on spectra

Smart Phase Mapping.

Dual Detectors
  • Mitigates shadowing and topographic artifacts
  • Option to merge spectra/compositional maps from both detectors
  • Doubles throughput count rate while maintaining single detector energy resolution
  • Better resolution stability versus systems with one detector with a large sensor
  • Averages quantitative analysis from two detectors to build more accurate results
Enhanced Linescan Acquisition


  • Configure spectra collection for efficient analysis of compositional gradients
  • Real-time overlay and scaling of the Linescan chart enables easy correlation of compositional data with image features
  • Avoid samples errors when you use Linescan with drift correction in the APEX Advanced software package

Live Drift Correction


  • Automatically set drift parameters for easy operation
  • Dynamically adjusts the correction frequency based on the drift magnitude for robust correction performance
  • Advanced correction options available to save drift images and define manual reference area
  • Available in Spectrum, Linescan, and Mapping modes for quality data in all collection modes
Spectrum Match


  • Use the optional feature to allow users to search through a spectrum library to find similar spectra
  • Simplify identification of unknowns by comparing them to potential candidates and reduce the complexity of finding discrepancies and similarities between spectra
  • Create and use your unique spectrum library for Spectrum Match
  • Match a collected “unknown” spectrum to a library of reference spectra using the Smart Materials and Minerals Library option
