Uranium atom and ion emission spectra resulting from the introduction of gaseous uranium hexafluoride (UF6) into an atmospheric-pressure argon afterglow discharge source have been acquired with the use of a high-resolution spectrometer. The isotopic splitting (235U/238U) of the uranium ion line at 424.437 nm has been utilized to analyze three different UF6 samples containing 0.245%, 3.80%, and 51.20% 235U, respectively. A limit of detection for UF6 in argon of ∼15 ppm for the U(II) 424.167-nm line has been achieved.
