Instructions for Using the XLS Measurement Uncertainty (MU) Calculator
Follow the steps below to calculate your measurement uncertainty (MU):
0. Specification of your Measurement Unit relevant to your analysis;
1. Determination of your repeatability/intermediate-precision
introduce your validation results (max 5 replicates per day; up to 10 days) obtained analysing a reference material (RM);
2. Determination of the bias
introduce the reference value and associated expanded uncertainty (k=2) of the RM,
Use the replicate results from day 1 by default;
3. Estimatation of your MU
introduce the average measurement result for your unknown sample,
together with the number of replicates obtained on one or several days.
