FWHM (Peak-width) versus Pass Energy (PE)
C (1s) FWHM from Poly-Butene polymer
FWHM changes with Pass Energy (PE) settings: 10, 50 and 200 eV
10 eV and 50 eV Pass Energies give almost the same FWHM. The natural FWHM for C (1s) is revealed by the 50 eV PE.
Three C (1s) peaks measured with three different PEs from Poly-butene, and Normalized to the same Peak Intensity.
Three C (1s) peaks measured with three different PEs from Poly-butene, and Normalized to the same Peak Intensity. BE Scale was Zoomed Horizontally.
Three C (1s) peaks measured with three different PEs from Poly-butene as measured. Not normalized.
The peak area for PE = 200 eV (red line) is many times larger than the peak area for PE = 10 eV (blue line).
