Difficulties/Challenges of EELS Measurements
- Practical Electron Microscopy and Database -
- An Online Book -



This book (Practical Electron Microscopy and Database) is a reference for TEM and SEM students, operators, engineers, technicians, managers, and researchers.



There are many difficulties in EELS measurements, e.g. beam damage and sample drift. Some problems are not so common but happen in some materials. For instance, in most cases, EELS measurement on Ce2O3 can be unsuccessful because of the rapid oxidation of the sample during its transfer into the TEM system. [1]

Practically, EELS analysis is much easier and probably more accurate if the core-loss edges of the elements in the specimen are well separated in energy.
