Popis:	A method was developed for the determination of hydrogen in uranium metal by mass spectrometry. The samples are introduced into a tube containing helium at atmospheric pressure. Hydrogen gas evolved from the heated sample is mixed with a helium gas stream flowing through the tube and over the sample at a constant rate. The effluent gas mixture is monitored at m/e2. The resulting rate-ofevolution curve is integrated with respect to time with an electronic integrator. The empirical number so obtained is directly proportional to the hydrogen content of the metal. The method was adapted to time-of-flight and magnetic mass spectrometers. The determination requires from 3 to 10 min on the mass spectrometer, depending on size of the sample and hydrogen content of the metal. Precision comparable to that of the classical vacuum technique is obtained. The technique described is also adaptable to the study of diffusion of hydrogen in uranium metal. (auth)
