EDXRF with an audio digitizer [PDF]

open access: yesX-Ray Spectrometry, 2011
We utilized an audio digitizer in energy‐dispersive X‐ray fluorescence (EDXRF) with a silicon drift detector and achieved a full width at half maximum (FWHM) of 178 eV at Mn Kα (92‐µs peaking time). To confirm the ability of EDXRF with an audio digitizer, we also examined energy versus ...

A Robust Cost-Effective Spectrophotometric Method for Nb Determination in Refractory Nb-doped Gadolinium Zirconate: Overcoming Matrix Dissolution Challenges. [PDF]

open access: yesAnal Sci Adv
ABSTRACT A simple, robust and cost‐effective analytical methodology was developed for the determination of niobium in highly refractory materials: Nb‐doped gadolinium zirconate (Gd2Zr2O7:Nb) and niobium pentoxide (Nb2O5). The challenge of digesting these matrices was successfully accomplished by establishing two independent dissolution procedures: (i ...
