Mass scans revealed that as much as several mole percent carbon monoxide, accompanied by H2O, can result from a reaction between H and carbon dioxide in experiments using all three reactants. A measurable O isotopic shift was detected in carbon dioxide samples where carbon monoxide was detected. Traditional means for measuring C-O-H volatile composition at the end of piston-cylinder experiments will not identify this chemical change in the volatile composition and may result in erroneous determination of fluid composition. Glass and witherite packing materials effectively maintained a low fH2 around the samples. This content is PDF only. Please click on the PDF icon to access.
