The Determination of X-Ray Observation of Bromine and Zinc Levels in Untreated Wheat Flour.

The recently developed method of trace element analysis by observation of characteristic X rays with a lithium-drifted silicon detector was used to study levels of heavy elements in wheat flour. The various samples obtained from a pilot mill were each found to contain quantities of zinc at levels of about 2 to 54 p.p.m. and bromine at levels of 2 to 14 p.p.m. An attempt is made to correlate these zinc and bromine concentrations to the standard analyses of ash content and protein level used for flour.
