The NMR data acquisition sensitivity depends on the NMR probe performance. Recently, a remarkable sensitivity enhancement was achieved by a cryogenic probe.122 This technology reduces the thermal noise of the NMR signal by cooling the device by liquid helium. In practice, the enhancement strongly depends on the sample condition. Usually, the S/N ratio increases by factors from two to four for protein solution.
