As a national metrology institute, KRISS has established robust SI-traceable analytical methods to characterize elemental contents in candidate reference materials. Isotope dilution (ID) inductively coupled plasma-mass spectrometry (ICP-MS) and neutron activation analysis (NAA) are two examples of well-established methods for elemental analysis in complex sample matrices. Although they are even regarded as potential primary methods due to their robustness and SI-traceability, the analysis results often suffer from unexpected biases depending on analytes and sample matrices. In the present talk, some examples of our continuing fights against small, but not negligible, measurement biases will be illustrated. It includes the importance of oxidation state equilibration and control of spectral/non-spectral interferences in the area of ID ICP-MS. Recent development of an exact matrix matching ICP-optical emission spectroscopy (OES) as an additional potential primary method of elemental analysis will be also presented.
