X-ray Fluorescence Spectrometer (XRF)

About

Location: Jesser Hall room 108

XRF spectrometer with a silver (Ag) anode x‐ray tube and 50 micron Be window performs non‐destructive identification and quantification (< 1 ppm) of elements from sodium (Na) to americium (Am) in solids, liquids, loose‐ and pressed‐powders. Silicon drift detector for secondary X-ray detection. Omnian standardless analysis software for peak ID and quantification.

XRF Technique Summary:
