Abstract
A device for attaching and detaching a cryogenic probe to and from a nuclear magnetic resonance (NMR) spectrometer. The device permits the probe to be loaded in the spectrometer in a shortened time and achieves high measurement throughput. The device has loading platforms (--) on which cryogenic probes (P, P) are loaded. Each loading platform has a horizontal drive mechanism, a vertical drive mechanism, and a spacing mechanism. The device further includes probe cooling devices (--) for circulating a refrigerant to and from the cryogenic probes (P, P) via transfer tubes (--) made of a flexible material, thus cooling the probes (P, P). A temperature-controlled gas feeder () supplies a temperature variable gas for temperature adjustment to the probes (P, P). A vacuum pumping system () evacuates the interiors of the probes (P, P) via vacuum pipes (--) made of a flexible material.
