Study of the Mode of Formation of Molecular Hydrogen in Nature.
Abstract
The problem is to determine the sources of planetary molecular hydrogen by (1) determining molecular hydrogen concentrations in seawater in the range of 10 to the -7th to 10 to the -11th power M with a precision of 1% or better and (2) determining the isotopic composition of molecular hydrogen from the atmosphere or other origins with a precision of 0.01% or better. The proposed method for determining seawater hydrogen concentrations was to use isotope dilution analysis, with deuterium as the diluting gas, followed by a mass spectrometric determination of the H2(+)/D2(+) ratio. The proposed method for determining the isotopic composition of atmospheric hydrogen was to extract the hydrogen from air as water and to make a mass spectrometric determination of the D(-)/H(-) ratio produced from the resulting water sample. We planned to use the same instrument for the positive and negative ion determinations.
