The isotopic ratio 34S/32S has been measured in cometary gas for a few comets, but it has only been measured in cometary dust by stardust.
The dust measurements find a value of the ratio that is consistent with
the Vienna Canyon Diablo Troilite value of 0.0442 within errors, but
there is more spread in the values from cometary gas. In this paper, we
present the result of measurements of the sulphur isotopic ratio in dust
from Comet 67P/Churyumov–Gerasimenko with the COSIMA instrument aboard
the Rosetta spacecraft. We find a result of 0.0463 ± 0.0057, which is consistent within errors with the terrestrial value.
