Abstract: The combustion- gravimetric method for the determination of hydrogen
has been modified and adapted to the measurement of hydrogen in molybdenum
metal. The sample is burned in oxygen at 11000 C. Fused magnesium oxide sand is
used to absorb the molybdic oxide produced and prevent its sublimation in the
combustion tube. The water produced by oxidation of the hydrogen present is
absorbed in anhydrous magnesium perchlorate and weighed. An average recovery of
99.l% with a standard deviation of 8 ppm was obtained for the analysis of 62
samples containing known amounts of hydrogen in the 10 to 500 ppm range.
