EDS Spectrum showing elemental peak height as a function of X-ray counts collected (LC)
Elements Identified Major (> 10%): carbon, oxygen, silicon. Minor (1-10%): aluminum, iron, potassium. Trace (< 1%): calcium, magnesium, phosphorus, titanium, sulfur.
Area X-ray counts collected: 1,007,987. Live Time: 17.0 seconds. Magnification: 1001x. 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.
