Sem - Chemical Analysis Ppt
Offers much higher energy resolution than EDS. It is better for identifying trace elements and separating overlapping peaks (e.g., Molybdenum and Sulfur).
Here is an outline of a PPT on SEM Chemical Analysis: sem chemical analysis ppt
Samples must be vacuum-compatible. Non-conductive samples usually require a thin carbon or gold coating to prevent "charging." Offers much higher energy resolution than EDS
While EDS is the standard, a comprehensive presentation should touch upon these advanced methods: sem chemical analysis ppt
The EDS detector counts these X-rays and sorts them by energy levels, creating a histogram or "spectrum." 2. Complementary Techniques
