The assay of deuterium in organic compounds has heretofore been based on combustion followed by reduction of the resultant D,O to deuterium, which is then measured in the mass spectrometer. Certain limitations in methods (1, 2) employing the combustion principle have led to consideration of another
The choice of model compounds for checking the recovery of dissolved organic and total dissolved phosphorus in natural waters is discussed. Ten compounds were compared for their recovery in fresh and seawater. Four different oxidative procedures were used: acidic and alkaline persulfate oxidation, c
