Abstract:
1. An NMR probe comprising: a probe case inserted to a bore portion of a superconducting magnet; a sample pipe insertion port surrounded by the probe case and provided for inserting a sample pipe thereto; a probe coil receiving a nuclear magnetic resonance (NMR) signal of a sample entering into the sample pipe, the probe coil being provided in an outer side near the center of the sample pipe insertion port; and a temperature modulated gas for controlling a temperature of the sample pipe capable of being supplied to the sample pipe insertion port, wherein a sample pipe insertion structure body constituted by a hollow portion and double pipes is provided in an inner side of the probe case, a flow division hole of the temperature modulated gas is formed in the sample pipe insertion structure body in such a manner as to place an inner and outer pipe of the double pipes in communication with the other, the sample pipe insertion port is formed by the hollow portion, the temperature modulated gas is supplied to a flow path between the double pipes, and the NMR probe is provided with a thermal anchor exchanging heat with the temperature modulated gas flowing through the flow path and connecting the probe case and the sample pipe insertion structure body.
