- Counts per second (CPS) map that illustrates variations brought on by surface features and provides a CPS distribution by displaying count rate quality at each pixel.
- CompoMaps provide more accurate representations of EDS maps by separating contributions from overlapping peaks to individual elemental maps.
- Activate and add elements quickly during mapping to make operation and inspection easier.
- During elemental mapping, choose from 40 color options to easily create vibrant images.
- Map several element lines (K, L, and M) at once.
Dynamic Element Mapping

- Interact in real-time to display only selected elements in Mapping and Linescan modes.
- During map collection, modify user-selected regions of interest, element lines, and elements.
Montage Large Area Mapping
- Use stage movements to gather data from several areas of analysis.
- Assemble data automatically into a single file for thorough examination.
Smart Phase Mapping

- No user setup is necessary.
- Gather spectra, elemental, and phase maps automatically
- Change the phases' names and color schemes.
- Use spectra to predefine or reanalyze phases.
Dual Detectors
- Reduces topographic artifacts and shadowing
- Combining the spectra and compositional maps from both detectors is an option.
- Maintains the energy resolution of a single detector while doubling the throughput count rate.
- Superior stability and resolution compared to systems using a single detector and a large sensor
- Builds more accurate results by averaging quantitative analysis from two detectors.
Enhanced Linescan Acquisition

- Set up the collection of spectra for effective compositional gradient analysis.
- The Linescan chart's real-time overlay and scaling make it simple to correlate compositional information with image characteristics.
- Prevent sample errors by utilizing Linescan with drift correction in the APEX Advanced software package.
Live Drift Correction

- Drift parameters are automatically set for convenience.
- For reliable correction performance, the correction frequency is dynamically changed according to the drift magnitude.
- Advanced correction options allow saving drift images and defining a manual reference area.
- Available in Spectrum, Linescan, and Mapping modes to ensure high-quality data across all collection modes.
Spectrum Match
- Make use of the optional feature that lets users look up related spectra in a spectrum library.
- Reduce the difficulty of identifying differences and similarities between spectra and make it easier to identify unknowns by comparing them to possible candidates.
- Create and customize spectrum library for use with Spectrum Match
- Use the Smart Materials and Minerals Library option to compare a gathered "unknown" spectrum to a collection of reference spectra
