Additionally I am worried by the table that states take-off angle is 90 degrees. EDS Spectra •Energy range of spectrum divided into channels (1024, 2048, 4096 on AZtec) • Energy width changes depending on energy range and number of channels •Intensity vs. Energy •Peaks for each characteristic x-ray of elements in sample. Specific bands may fall over a range of wavenumbers, cm-1. The spectra are processed to remove Bremsstrahlung X-rays and spectral artifacts, and then the Characteristic X-rays are compared with data measured from standard reference materials. This example uses an EDS-SEM spectrum of a a test material (EDS-TM001) provided by BAM. The most sensitive or ultimate lines for many spectra lie in the vacuum-ultraviolet region (wavelength < 2000 Å). How to deal with the C and O in the EDS which normally gives its wrong values?
