accurate analysis of the protium-deuterium (HD) component. Data collected by the
high-resolution mass spectrometer and gas chromatograph analysis were included in
Tables 2 and 3, respectively.
Half of the protium-deuterium value from the mass spectrometry analysis was
added to either the molecular hydrogen or molecular deuterium value. These calculated values were then compared to the results generated from the gas chromatograph
analysis (Table 4).
Testing to evaluate the new analytical technology was performed with a mixture
containing protium, protium-deuterium, and molecular deuterium to determine the
efficiency of this technology in the presence of protium-deuterium upon isotope
separation in the Thermal Cycling Absorption Process system. The results shows
that the gas chromatograph column with deuterium carrier gas measures a value
