Vacuum technology considerations for mass metrology

Abstract
Vacuum weighing of mass artifacts eliminates the necessity of air buoyancy correction and its contribution to the measurement uncertainty. Vacuum weighing is also an important process in the experiments currently underway for the redefinition of the SI mass unit, the kilogram. Creating the optimum vacuum environment for mass metrology requires careful design and selection of construction materials, plumbing components, pumping, and gauging technologies. We review the vacuum technology required for mass metrology and suggest procedures and hardware for successful and reproducible operation.Citation
