Popis:	A probe has been developed to determine the solubility of hydrogen in metals. The method is based on mass balance and high-pressure hydrogen produced in situ partitioning between a zirconium probe and the metal. As an example, the solubility of hydrogen in copper, SH in Cu, has been determined between 350 and 450 °C: $$ S_{\text{H\,in\,Cu}} = (1000 \pm 200)\exp \left( { - \frac{43000 \pm 1300}{RT}} \right){\text{ [mol H}}_{2} /{\text{m}}^{3} \sqrt {\text{MPa}} ]. $$ This solubility agrees with permeation and diffusivity measurements spanning 10 and 6 orders of magnitude, respectively.
