Abstract
A probe head in a nuclear magnetic resonance measurement apparatus includes a rotating mechanism. In the probe head, an exhaust gas having a high temperature or a low temperature is discharged from a discharge port of the rotating mechanism. An additive gas having room temperature is introduced into the probe head through a plurality of ejection holes. The additive gas is mixed with the exhaust gas, and, as a result, an exhaust gas mixture having a temperature closer to room temperature than is the temperature of the sample is produced. A deflector regulates the direction in which the exhaust gas flows.
Claims14
A nuclear magnetic resonance measurement apparatus comprising:
- a structure body having a sample space, the space being configured to house a sample that is to be measured by nuclear magnetic resonance, into which a sample gas for adjusting a temperature of the sample to a predetermined temperature is introduced;
- a container of a nuclear magnetic resonance measurement probe configured to house the structure body;
- and
- an exhaust gas processing mechanism comprising an additive gas generator for generating an additive gas and an additive gas pipe provided between the additive gas generator and the container and configured to feed the additive gas into the container,
- wherein the exhaust gas processing mechanism is configured to mix the additive gas with an exhaust gas that is the sample gas exiting from the sample space, to generate an exhaust gas mixture having a temperature that is closer to room temperature than is the predetermined temperature.
A method for processing an exhaust gas in a nuclear magnetic resonance measurement apparatus, the method comprising:
- introducing a sample gas for heating or cooling a sample that is to be measured by nuclear magnetic resonance, into a sample space that houses the sample to adjust a temperature of the sample to a predetermined temperature, the sample space defined by a structure body housed within a container of a nuclear magnetic resonance measurement probe;
- feeding an additive gas into the container via an additive gas pipe provided between an additive gas generator and the container;
- mixing the additive gas with an exhaust gas that is the sample gas exiting from the sample space, to generate an exhaust gas mixture having a temperature that is closer to room temperature than is the predetermined temperature;
- and
- exhausting the exhaust gas mixture.
