Samples of bone ash were mixed with anhydrous copper sulfate and graphite and pelleted. A d-c arc was used to excite the spectra which were then evaluated by microphotometry. The effective concentration range was 50 to 350 ppm of strontium in the seh, and the coefficient of variation was 6% for single exposures at the 90 ppm level. In the case of milk and vegetation, strontium and calcium were separated as insoluble oxalates, and the strontium content of this fraction was determined by a methcd similar to that used for bones. This methcd had a similar range and accuracy. An alternative fiame photometric method is described for the determination of strontium in the calciumstrontium oxalate fraction, the coefficient of variation of the whole analytical operation being 5%pede examination.
