Instructions for Using the XLS Measurement Uncertainty (MU) Calculator

Follow the steps below to calculate your measurement uncertainty (MU):

1. Specify your Measurement Unit relevant to your analysis.
   

2. Determine Your Uncertainty Function:

   • Input 15 measurement results from routine samples: 6 at low content and 9 at high content.
   • Each sample must be measured twice (provide two results per sample).

3. Calculate Your Bias:

   • Input up to 7 replicate measurement results of the reference material (RM).
   • Provide the reference value and its associated expanded uncertainty (k=2).

4. Estimate Your Measurement Uncertainty to report (MU):

   • Input the measurement result value to estimate the MU.

Note:
Microsoft does not allow to 'copy & paste' cells into the online spreadsheet.
All values must be entered manually, one at the time, into the designated yellow cell ONLY.
Please note that your inputss will not be saved; the spreadsheet will be reset (clearing all values) each time you leave or refresh this page.
