Determination of 25 Trace Element Concentrations in Biological Reference Materials by ICP-MS following Different Microwave-Assisted Acid Digestion Methods Based on Scaling Masses of Digested Samples

<table>Statistical variability estimated for each quantifiable analyte in matrices TL and MT. The resulting magnitude can be compared for the different masses ranging from 100 up to 900 mg (the smaller mass amounts produced overall higher relative uncertainties).</table>
