The 3He/4He ratio of the new internal He Standard of Japan (HESJ)
Geochemical Journal, Vol. 36, No. 2, P. 191-195, 2002
ABSTRACT
We have prepared an artificial mixture of 3He and 4He to be used as an internal standard for precise 3He/4He measurements of terrestrial mantle-derived samples. The mixture is named HESJ (He Standard of Japan). The 3He/4He ratio of HESJ was determined by obtaining the weighted average of repeated analyses from five machines in four laboratories in Japan. The recommended value of the 3He/4He ratio of HESJ relative to the air value (R/Ra) is 20.63 ± 0.10. HESJ is available to all researchers.- Published : 2002-04-20
