Abstract

This paper describes a new approach to directly link air and vacuum mass measurements using magnetic levitation techniques. This procedure provides direct traceability to national standards, presently defined in air, without requiring the estimate of surface effects presently used to evaluate vacuum artifacts. We describe the basic principles, challenges, initial modeling calculations, and performance expectations.
