摘要： A nuclear magnetic resonance apparatus incorporating a first trans-receiver coil, an internal lock coil, a decoupling coil, means for tuning said coils to desired frequencies, a first trans-receiving system for supplying the first trans-receiver coil with a first nuclear (such as .sup.1 H) resonance RF wave and detecting the first nuclear resonance F.I.D. signal, a second trans-receiving system for supplying the first trans-receiving coil with a second nuclear (such as .sup.13 C) resonance RF wave and detecting the second nuclear resonance F.I.D. (Free Inductance Decay) signal, a third trans-receiving system for supplying the internal lock coil with a third nuclear (such as .sup.2 D) resonance RF wave and detecting the third nuclear resonance signal, and a transmission system for supplying the first nuclear resonance RF wave to the decoupling coil, it being possible in said apparatus to observe different types of nucleus, viz; .sup.1 H and .sup.13 C without removing the internal lock by employing a third nucleus such as .sup.2 D so that the first and second nuclear spectrum can be observed at high resolution by first nuclear decoupling.

摘要： There is disclosed an NMR cell system for supercritical fluid measurements. This cell system has an NMR cell in which convection is prevented. A reactive gas and a reactive liquid can be smoothly introduced into the NMR cell. The oxygen (air) inside the NMR cell can be removed before measurement. The NMR cell system comprises a cylindrical cell, a cell holder, and an external pumping system. The cylindrical cell and the cell holder are made of a nonmagnetic material that withstands high temperatures, high pressures, and strong acidity. A pipe is mounted inside the cell holder to connect the external pumping system into the cell. A high-pressure cell for use with an NMR spectrometer is also disclosed. This high-pressure cell comprises a pressure-proof cell for receiving a sample, a pressure transfer tube for transmitting pressure to the sample in the cell, and a coupling portion for coupling together the pressure-proof cell and the tube. The pressure-proof cell is detachably mounted to the coupling portion via a sealing member.
