X-ray fluorescence and potentiometry compared for determining iodine content of thyroid glands.
We compare results for iodine quantitation by x-ray fluorescence of excised thyroid glands with results of the quantitation by means of an original, newly developed chemical method, a Schöniger combustion technique, in which iodie is quantitated potentiometrically. Subsequently, we establish the accuracy and clinical suitability of the former technique in quantifying the intrathyroidal iodine.
