Summary A universally usable, quantitative assay for deuterium-labeling work demands a stoichiometrical transformation of all samples into elementary hydrogen. For the detector, it is the best to connect directly a fractometer, that works with a catharometer cell. Tests with several carrier gases and an attempt with a palladium-black column failed; a molecular sieve with ordinary hydrogen as carrier was appropriate. The fractogram, written by a compensograph, shows a well gaugeable peak which is linearly proportional to the deuterium content of the sample. The error at full deflection amounts to ±0,5%. Protium deuteride, HD, is acting as if it were 1/2 D2, a fact that was confirmed by mass-spectrometric measurements.
