This certified reference material has elements with a range. The mass fraction of these elements is not constant over the entire cast. This is the reason for the relatively large uncertainty for the certified values of these elements. For the marked elements each disc has individually certified values with a smaller uncertainty. Those values are available on special-certificates (to be ordered individually for each disc). here - S-certificates only. Add an "S-Certificate" to your shopping cart together with your article, to get individually certified values for those elements.
