ABS resin pellet certified reference materials (CRMs, NMIJ CRM 8102-a, 8103-a, 8112-a and 8113-a) were developed in this study. Both the sample pretreatment procedure and the measurement one for the determinations of Cd, Cr, Hg and Pb in candidate ABS resin pellet RMs were examined, and several analytical methods, including isotope dilution mass spectrometry (a primary method of measurement), were developed. The analytical results obtained by several analytical methods showed good agreement within the uncertainty estimated for each analytical method. Consequently, it is concluded that these analytical methods established for the determinations of Cd, Cr, Hg and Pb in this study are reliable with high accuracy. From these results, the ABS resin CRMs developed in this study are SI traceable and have international consistency.
