EDS Spectrum showing elemental peak height as a function of X-ray counts collected (LC)
Elements Identified Major (> 10%): oxygen, carbon, calcium, sulfur Minor (1-10%): NA Trace (< 1%): NA
Area X-ray counts collected: 1,052,590 Live Time: 49.4 seconds Magnification: 500x Analyzed using Oxford X-Max80 energy-dispersive X-Ray spectroscopy (EDS) and Oxford AZtec platform software. Pigment sample was applied to carbon tape and mounted onto aluminum examination stub. X-rays from sample were excited by a 20 kV SEM electron beam in a low vacuum chamber (10 Pascal). The resolution of the X-Max80 silicon drift detector is 123 eV at MnKα wavelength.
