Determination of the Deuterium Abundances in Water from 156 to 10,000 ppm by SIFT-MS
Original language description
In response to a need for the measurement of the deuterium (D) abundance in water and aqueous liquids exceeding those previously recommended when using flowing afterglow mass spectrometry (FA-MS) and selected ion flow tube mass spectrometry (SIFT-MS) (i.e. 1000 parts per million, ppm), we have developed the theory of equilibrium isotopic composition of the product ions on which these analytical methods are based to encompass much higher abundances of D in water up to 10,000 ppm (equivalent to 1%). Thishas involved an understanding of the number density distributions of the H, D, O-16, O-17 and O-18 isotopes in the isotopologues of H3O+(H2O)(3) hydrated ions (i.e. H9O (4) (+) cluster ions) at mass-to-charge ratios (m/z) of 73, 74 and 75, the relative ion number densities of which represent the basis of FA-MS and SIFT-MS analyses of D abundance.
