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
Figure 1
Examples of linear regression for a selected group of elements measured in MT matrix: (a) elements with noncompatible with zero ordinate in the origin at 99% CL and (b) elements with compatible with zero ordinate in origin at 99% CL. See text for explanation. Analyte concentrations are reported as a mean value and standard deviation from the three analytical replicates.
