ENHANCED EELS & EDX SPECTROSCOPY

Beam Precession with DigiSTAR may enhance EELS & EDX signal reducing channeling effects. EELS quantification possible via TOPSPIN model based EELS quantification.

Beam Precession in EELS & EDX spectroscopy enhance the signal reducing channeling effects. Automated quantification with statistical error analysis is available. Multiple scattering derived from an automatically measured relative thickness.

MODEL BASED EELS QUANTIFICATION

Highly-automated EELS elemental analysis

Minimal user input required
Specify elements to quanitfy
Chemical shift of each elemental edge
Automated quantification with statistical error analysis
Multiple scattering derived from an automatically measured relative thickness
Elemental core-loss edges from several possible sources :
Theoretical : Hartree-Slater (Rez)
Experimental edges from reference materials
Intuitive workflow
