Measuring oxygen yields of a thermal conversion/elemental analyzer‐isotope ratio mass spectrometer for organic and inorganic materials through injection of CO

05.12.2014 | Xijie Yin, Zhigang Chen, Journal of Mass Spectrometry, 2014

The thermal conversion/elemental analyzer‐isotope ratio mass spectrometer (TC/EA‐IRMS) is widely used to measure the δ18O value of various substances. A premise for accurate δ18O measurement is that the oxygen in the sample can be converted into carbon monoxide (CO) quantitatively or at least ...
