APEX Software for EDS

APEX Screenshot

APEX™ is EDAX's premier software program for the collection and analysis of Energy Dispersive Spectroscopy (EDS) data and the compositional characterization of materials. APEX ensures high-quality, accurate results and increased productivity with its easy to use interface, live-time graphical display, and simultaneous review mode analysis.

Ease of Use

  • Intuitive operation for novice and expert users
  • Acquire and report data with as little as one mouse click
  • Automate routine tasks for quick and easy analysis
  • Ensure everyone has the right level of access with profile-based logins; from individual users to administrators


  • Selectable color scheme to match the Scanning Electron Microscope (SEM) interface or user preferences
  • Display configuration options to show data according to user preferences
  • Resize and arrange data windows according to your requirements


Simultaneous Live and Review Mode

Improve the efficiency of your experiment by simultaneously collecting a spectrum, linescan, or map while you evaluate data and generate reports.

Real-Time Results

  • Immediately identify and display elements using Element ID
  • Dynamically edit elements for the most accurate and efficient analysis
  • Easily understand your sample's composition using the live quantification statistics and graphical results
Graph quant result Graphical representation and statistical analysis of quantification results

Smart Quant

  • Use ZAF-corrected spectral analysis for quantitative compositional information
  • Simultaneously perform quantitative analysis during spectral data collection with no delay in the acquisition

Full Standards Quant

  • Flexibility to search, select, and combine standards
  • SmartStandards mode for intelligent selection of best fitting standards for accurate quantification results

Multipoint Analysis

  • Utilize Survey mode to perform point sampling quickly
  • Mark and analyze several locations on a sample to improve your data collection efficiency
  • Save and recall Multipoint scan lists to automate data collection and analysis

Data Management and Reporting

  • Project tree storage for seamless management of all data
  • Project exports to *.hdf file format
  • Save windows with one-click as *.bmp, *.jpg, *.png, or *.tif images

Advanced Reporting

  • Directly generate reports from the APEX Live mode to shorten your time to results
  • Use Report Designer to customize presentation templates for images, spectra, quantification results, text, logos, and sample information
  • Easily compare data from multiple areas or samples in the same report
  • Combines multiple templates to display results easily
  • Automatically create reports immediately after data collection is complete

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
Dual detectors

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
