  • Publication number: 20230050786
    Abstract: An NMR spectrum is acquired from a nucleus of interest in a solvent included in a sample solution. A spectrum analyzer analyzes a number of splits, a splitting interval, a number of signals, and a signal interval based on the NMR spectrum. Based on these characteristic quantities, an identifier identifies the solvent. In another configuration, a plurality of NMR spectra acquired from a plurality of nuclei of interest included in the solvent may be analyzed.

  • Patent number: 10302721
    Abstract: Procedure instruction sequences (P1˜PN) in an instruction sequence (for example, an instruction sequence for an NMR spectrometer) are generated in a precedential manner, and transferred to a procedure storage area on a transmission and reception unit in a precedential manner. After the precedential transfer, a remaining portion of the instruction sequence (streaming instruction sequence (SM1, . . . )) is sequentially generated in predetermined units from the beginning, and sequentially transferred to a FIFO area on the transmission and reception unit. A sequencer refers to the streaming instruction sequence, executes the instruction, and refers to a procedure instruction sequence on the procedure storage area.

  • Patent number: 10132896
    Abstract: In a magnetic resonance measurement apparatus, a plurality of transmission signals are combined to generate a digital combined signal. The digital combined signal is converted into an analog combined signal by a D/A converter. The signal includes, for example, a first pulse of a rectangular shape and a second pulse of a mountain shape. During measurement, an operation of a dynamic variable attenuator is changed immediately after the first pulse. With this process, the second pulse is suppressed, and a suppressed second pulse is generated.
