Abstract:
1. An apparatus of nuclear magnetic resonance measurement by using circulation flow for sample condition control, comprising: a magnet for applying a magnetic field to a sample to be measured; a bore placed at a hollow portion of the magnet; a nuclear magnetic resonance probe, at least a portion of which is placed in the bore; an NMR measurement portion placed at a portion of the nuclear magnetic resonance probe and equipped with a container having a sample injection port for injecting the sample and a sample discharge port for discharging the sample; a first sample transfer tubing connected to the sample injection port for transferring the sample to the NMR measurement portion; a mixing filter portion connected to the first sample transfer tubing for mixing a sample solution with a small molecule solution to prepare the sample; and a receiver/transmitter apparatus for transmitting an electromagnetic wave to the NMR measurement portion or receiving an electromagnetic wave from the nuclear magnetic resonance probe, wherein nuclear magnetic resonance measurement is performed by irradiating the electromagnetic wave to the sample injected into the NMR measurement portion via the first sample transfer tubing connected to the mixing filter portion.
