Matrix Spike (MS)/Matrix Spike Duplicate (MSD) analyses are used to determine the accuracy (MS) and precision (MSD) of a analytical method in a given sample matrix. Therefore, the usefulness of this report is limited to samples of 

similar matrices analyzed in the same analytical batch.

NA = Indicates %RPD could not be calculated

%RPD = Relative Percent Difference
