IXRF EDS Integration for LEO
The Integrated EDS system combines the LEO 1400's and 1500's series SEM and IXRF EDS
user interfaces into a single application. The EDS toolbar is accessed directly
from the SEM user interface allowing advanced microanalysis features to be
performed directly on the live SEM image. All EDS data can be stored in a single file.
Advanced Features (included with every system)
- Quantitative EDS, X-ray Mapping, and Linescan analysis in a single application
- Complete spectrum processing including escape and sum peak removal, automatic background removal, and net peak extractions using Gaussian deconvolution
- Quantitative analysis using ZAF, with or without standards
- Quantitative Spectral Matching
- Automated acquisition and analysis of spectra from selected spots or areas on the image
- Definable Phase X-ray Mapping by Wt%
- FastMap technology stores all spectral data with each X-ray Map pixel (PTS Maps)
- FastLinescan technology stores all spectral data with each linescan point (PTS Linescans)
