EDS Spectrum showing elemental peak height as a function of X-ray counts collected (LC)
Elements Identified: Major (> 10%): oxygen, carbon, arsenic. Minor (1-10%): sulfer, silicon, calcium. Trace (< 1%):NA.
Area X-ray counts collected:1,007,569. Live Time:12.2s. Magnification:502x. 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 Pascals). The resolution of the X-Max80 silicon drift detector is 123 eV at MnKα wavelength.
