The “GPMA” samples distributed by the Research Institute of Applied Physics (Irkutsk) for collaborative study were analysed for forty four elements by X‐ray fluorescence spectrometry (XRF) and instrumental neutron activation analysis (INAA). Analytical data obtained are presented along with a description of the analytical procedures for the two methods. For elements analysed by both techniques, generally favourable agreement is observed with, however, some exceptions. Small systematic discrepancies are noted for Co, Ba which are likely to be caused by small differences in the calibration response of the two techniques. Routinely in INAA, GS‐N was used as the primary calibration standard while reference materials BE‐N, AC‐E and GXR‐4 were analysed concurrently to assess the traceability of results. Mean values obtained for these reference materials during the last 15 0 runs show good agreement between measured and accepted values.
