“At this incident energy of 13025 eV, the energy resolution was ~1.4 eV.”

should read:

“At this incident energy of 13025 eV, the experimental setup made use of a multilayer monochromator with an energy resolution of ~80 eV.”

“The sample matrix was approximately modeled with reference to Au foil (density = 19.32 g/cm3).”

should read:

“The sensitivity of the measurement, allowing the determination of elemental concentration from measured X-ray fluorescence counts, was calibrated using an Au foil (thickness = 9.94 nm; density = 19.32 g/cm3).
