Abstract

There is disclosed an NMR probe including a body defining an internal chamber. This chamber is adapted for supporting a vacuum and the body is of a non-magnetic material. A conduit extends through the chamber in the body. The conduit has a first portion in communication with second portions, the first portion being intermediate the second portions, with the first and second portions of non-magnetic materials with substantially equal thermal expansion coefficients. An RF coil is positioned along at least a substantial portion of the first conduit portion. It is preferred that this device also include a field or frequency lock unit in the chamber, as well as a getter, to allow for degassing in the chamber to maintain the preferred high pressure vacuum. A method of using this NMR probe for NMR analysis is also disclosed.
