  • Patent number: 9645065
    Abstract: A flow analyzer includes a flow container, a fluid-introducing section that introduces an introduction target fluid into the flow container, a fluid control section that performs a control process that cyclically changes the flow rate or the fluid pressure of the introduction target fluid that is introduced into the flow container from the fluid-introducing section, a discharged fluid analysis section that performs a component analysis process on a discharged fluid that has been discharged from the flow container, and a frequency analysis section that performs a frequency analysis process on a discharge profile, the discharge profile being obtained from control information about the introduction target fluid and analysis results for the discharged fluid, and representing the relationship between the component ratio in the discharged fluid and time.

  • Patent number: 7605001
    Abstract: There is disclosed an NMR measurement method of observing plural magnetization transfer patterns in one experiment and observing their respective time-modulated, evolved chemical shifts. In an earlier portion of a pulse sequence, a transition is made from in-phase magnetizations to antiphase magnetizations using RF pulses. In an intermediate portion of the sequence, the antiphase magnetizations are interchanged using 90° RF pulses. In a later portion of the sequence, a transition is made from the antiphase magnetizations to the in-phase magnetizations using other RF pulses. Simultaneously with the interchange of the magnetizations, evolution of chemical shifts is performed by a constant-time evolution technique. In the earlier and later portions of the pulse sequence, evolutions of the chemical shifts can be performed simultaneously because the magnetizations of two nuclei are in lateral magnetization state.

  • Patent number: 7106059
    Abstract: A method is offered which is capable of quantifying all the peaks of a magnetic resonance spectrum based on a theoretical relationship between the real and imaginary parts of the spectrum without phase correcting the peaks. First, the spectra of the real and imaginary parts are found by quadrature detection. Then, integrated values a and b over given regions of the obtained spectra of the real and imaginary parts, respectively, are found. An integral intensity of a spectral peak in the spectrum is calculated to be ±?{square root over ((a2+b2))}.
