EDS Mapping

  • Counts per second (CPS) map displays count rate quality at every pixel presented to offer a CPS distribution and highlights differences caused by surface features
  • CompoMaps separate contributions from overlapping peaks to individual elemental maps for more precise representations of EDS maps
  • Users can choose from 40 color options to easily develop vibrant images during elemental mapping
  • Users can quickly activate and incorporate elements while mapping to streamline operation and inspection
  • Concurrently map numerous element lines (K, L, M)

Montage Large Area Mapping

  • Large areas can be scanned using stage movements to gather several fields of analysis
  • Data stitching can be automatically performed into a single file for detailed analysis

Smart Phase Mapping

  • User setup is not required
  • Elemental, spectra, and phase maps can be automatically collected
  • The name and color selection of phases can be customized
  • Phases can be predefined or reanalyzed based on spectra

Dual Detectors

  • Minimizes shadowing and topographic artifacts
  • Option to combine spectra/compositional maps from both detectors
  • Averages quantitative analysis from two detectors to build more precise results
  • Greater resolution stability versus systems with one detector with a large sensor
  • Doubles throughput count rate while sustaining single detector energy resolution

Enhanced Linescan Acquisition

  • Real-time overlay and scaling of the Linescan chart facilitates easy correlation of compositional data with image features
  • Spectra collection can be configured for the efficient examination of compositional gradients
  • Samples errors can be avoided when users use Linescan with drift correction in the APEX Advanced software package

Spectrum Match

  • Users can create and use unique spectrum library for Spectrum Match
  • The optional feature enables users to search a spectrum library to locate similar spectra
  • A collected “unknown” spectrum can be matched to a library of reference spectra using the Smart Materials and Minerals Library option
  • Streamlines identification of unknowns by comparing them to possible candidates and reduces the complexity of detecting inconsistencies and similarities between spectra
