Enabling scientific discovery through stable isotope analysis

O₂ gas from a compressed cylinder originating from Praxair in Seattle, Washington.

Here is a table of all laboratories that have measured this gas, the results they obtained, and information provided about their reference materials. ± indicates standard deviation. ¹⁷O_excess was calculated as (ln(δ¹⁷O/1000+1)-0.528*ln(δ¹⁸O/1000+1))*1000000 and are in units of permeg.
