Abstract
A microwave add digestion method for the preparation of biological samples for PIXE analysis is presented. The precision and accuracy of the entire PIXE analytical procedure, including the microwave digestion step, were evaluated by analyzing eight certified reference materials. For elements heavier than K, and for concentration levels from 2 jxg/g upward, the total random error of a single analysis is in the range of 2 –5%. The accuracy is better than 5%. The detection limits are down to 0.3 μg/g.
