Simultaneous Live and Review Mode
In APEX™, a spectrum, linescan or map can be collected while users work simultaneously with existing data and generate reports, thus saving time and increasing efficiency.
Easy to Interpret Data
  • Live-time spectrum display with Element ID showing which elements are found in the analysis
  • Live-time dynamic element editing for the most accurate and efficient analysis
  • Live-time quantification values shown together with charts or graphs for easy understanding of the measured composition
Graphical representation and statistical analysis of quantification results.

Advanced Reporting
  • Reports can be generated directly from APEX™ Live mode for efficient data workflow
  • Report Designer provides customizable templates for images, spectra, quantification results, text, logos, and sample information for the flexible presentation of data
  • Data from multiple areas or samples can be sent to the same report for easy comparisons
  • Multiple templates can be combined to easily display results according to user preferences
  • Automatic report generator mode creates reports immediately at the completion of data collection

EDS Mapping
  • Counts per second (CPS) map showing count rate quality at every pixel displayed to provide a CPS distribution and allow a unique view of map data to explain variations caused by surface features
  • CompoMaps for separation of elemental contributions from overlapping peaks to individual elemental maps for more accurate representations of EDS maps
  • Easy activation and addition of elements while mapping to simplify operation and inspection
  • Selection from 40 color options for elements allows the easy creation of vibrant images during mapping
  • Simultaneous mapping of multiple element lines (K, L, M)
Dynamic Element Mapping
  • Addition and removal of elements while in Mapping and Linescan modes to show only elements of interest
  • Ability to edit elements, element lines, and user selected regions of interest during map collection

Smart Phase Mapping
  • No user setup required
  • Spectra, elemental and phase maps collected automatically
  • User-defined naming and color selection of phases
  • Ability to predefine or reanalyze phases based on spectra
Linescan Acquisition
  • Collection of spectra along a user-defined line with configurable parameters for efficient analysis of compositional gradients
  • Linescan chart overlay is updated live on the image and scaled to the selected line for easy correlation of compositional data with image features
  • Linescan can be used with drift correction in the APEX™ Advanced software package to avoid errors due to sample drift

Drift Correction
  • Drift parameters automatically set for easy operation
  • Correction frequency adjusted dynamically based on drift magnitude for robust correction performance
  • Options to save drift images and define manual reference area for advanced correction needs
  • Available in Spectrum, Linescan, and Mapping modes for quality data in all collection modes
Spectrum Match
  • Optional feature allowing users to search through a spectrum library to find similar spectra
  • Identification of unknowns simplified by comparing them to a group of potential candidates and reducing the complexity of finding discrepancies and similarities between spectra
  • Ability for users to create their own spectrum library to be used for Spectrum Match
  • Smart Materials and Minerals Library option enables the matching of a collected “unknown” spectrum to a library of reference spectra
