Abstract
An improved procedure of 18O/16O ratio measurements by means of oxygen conversion to CO2 is developed, which allows one to obtain the true δ180 values with a precision of ±0.05‰ in oxygen samples down to 7 μmol. The isotopic exchange between quartz glass and oxygen gas was measured in the temperature range of 600-900°C, and it was found to be less than 0.2%.
