Analysis of individual thyroid tablets.
A procedure was developed for the assay of individual thyroid tablets or composite samples equivalent to as little as 0.033 g (0.5 gr) of thyroid. The sample is ignited in a closed atmosphere of oxygen and, after a series of redox reactions, the iodine is determined spectrophotometrically as the triiodide ion. The results agree well with those obtained by the USP thyroid tablet assay.
