Tables supporting improved EA-Cr_HTC hydrogen-isotope technique for halogen- and S-bearing organic compounds

Accurate hydrogen isotopic analysis of halogen- and sulfur-bearing organics has not been possible with traditional high-temperature conversion (HTC) because the formation of hydrogen-bearing reaction products other than molecular hydrogen (H2) is responsible for non-quantitative H2-yields and possible hydrogen isotopic fractionation. The elemental analyzerchromium/high temperature conversion reactor was substantially modified for the conversion of halogen- and sulfur-bearing samples. The modified reactor setup showed an overall hydrogen-recovery of more than 96 percent for all halogen- and sulfur-bearing organic compounds. Supporting analytical results and other information demonstrates the high quality performance of the modified reactor setup.
