The metrological compatibility of n(234U)/n(238U), n(235U)/n(238U) and n(236U)/n(238U) isotope amount ratio measurement results performed by gas source mass spectrometry (GSMS), thermal ionisation mass spectrometry (TIMS) and multi-collector inductively coupled plasma mass spectrometry (MC-ICPMS) in a set of low-enriched uranium samples is demonstrated in this study. The impact of the correlation between the certified isotope ratio materials on the metrological compatibility of measured isotope amount ratios is also discussed. The metrological concepts defined in the VIM 3rd edition and the measurement uncertainty evaluation according to the BIPM-ISO-GUM guide was thoroughly applied in this work.
