Abstract

A detailed description is given of an approach to uncertainty calculation for isotope dilution mass spectrometry (IDMS). This is applied to a real life example: measurement of the amount of copper in a candidate certified reference material (Antarctic sediment) using inductively coupled plasma (ICP)-IDMS after microwave digestion of the sample. An attempt is made to systematically implement the ISO guide, by defining the measurand, identifying and assessing uncertainty sources and combining them. The definition of IDMS as a primary method of measurement specifies the need for a complete uncertainty statement. An attempt was made to put this into practice.
