| Abstract: | The most commonly encountered difficulties for the quantitative measurement of zinc in biological samples are the limited
sample amount, total and effective digestion of connective and fatty residues, and low zinc concentrations. These problems
often lead to the determination of lower zinc values than actually present, so that the sample preparation, digestion, and
analytical procedure deserve careful attention.
In this short communication, a new method for microwave tissue disintegration is described. The authors have obtained consistent
and reproducible results with tissue samples of 0.5 g or less. |
