11.6.6 Standards Results
The quality control results for the standards are given in Table 11.3. As mentioned
previously, the historical statistics compare favourably with the original round robin
statistics generated for the RER standards. The bias between the two sets of means
is within 8.5 percent with one exception. Analyses of the RE10001X standard are
biased 27.7 percent higher than the original round robin analyses. This reflects the
change in protocol in that lab since the original round robin certification, which will be
discussed below. The RSD’s are all less than 5 when including analyses at both ALS
and Actlabs. There are less than 17 samples for any given standard, which exceed
the warning control limit of the mean ± 2 standard deviations (or well below the 5%
failure limit). A very limited number of samples (less than 1%) exceed the mean ± 3
standard deviations. Standards analyses show acceptable accuracy for resource
estimation.
