摘要： PROBLEM TO BE SOLVED: To provide a flow type NMR cell system for supercritical fluid measurement and a cell capable of introducing a sample into the cell easily with excellent repeatability by using the high pressure cell in a flow type.
SOLUTION: A necessary pressure is set by a back pressure regulator, and a fluid is sent into the cell by a pressure pump. In this case, since the fluid passes through a sample feeder on the way, the sample is also dissolved into the fluid and sent. When a target pressure is attained, the probe temperature is raised and the necessary supercritical state is generated. When the first gateway 1 is selected as an inlet and the second gateway 2 is selected as an outlet, a turbulent flow is generated because the sample goes out from a passage in the center of a narrow capillary to a wide sample observation region, to thereby heighten the agitation efficiency of the fluid, and to acquire a suitable state for stop-and-flow measurement. When the second gateway 2 is selected as the inlet and the first gateway 1 is selected as the outlet, the fluid flows in through a narrow clearance and a wider area compared with the capillary, and the fluid flows slowly from the upper side of the sample observation region, to thereby generate a laminar flow, and to acquire a suitable state for measurement in the flow.

摘要翻译：要解决的问题：提供一种用于超临界流体测量的流动型NMR电池系统和能够通过使用流动型高压电池容易地以优异的重复性将样品引入电池的电池。
解决方案：背压调节器设定必要的压力，流体通过压力泵送入电池。在这种情况下，由于流体在路上通过样品进料器，样品也溶解在流体中并送出。当达到目标压力时，探头温度升高并产生必要的超临界状态。当第一网关1被选择为入口并且第二网关2被选择为出口时，由于样本从窄毛细管的中心的通道出射到宽的样本观察区域，所以产生湍流，由此提高流体的搅拌效率，并获得停止和流量测量的合适状态。当选择第二网关2作为入口并且选择第一网关1作为出口时，与毛细管相比流体流过窄的间隙和更宽的区域，并且流体从样品的上侧缓慢流动观察区域，从而产生层流，并获得适合的流量测量状态。版权所有（C）2005，JPO＆NCIPI

摘要： PURPOSE:To improve the resolving power without lowering for an SN ratio, by using a function of an odd number degree of the third degree or more making the central part of sample of the starting point as a gradient of a magnetic field applying on the static magnetic field repeatedly. CONSTITUTION:Driving pulse is generated at a prescribed timing from an energizing pulse generation circuit 7 by a timing circuit 10 and a switching circuit 9 is brought down for the A side synchronizing with it and then, said pulse is irradiated on the sample in a sample tube 1 and also, a gradient of a magnetic field is sloped by turning a power source 6 on in the same timing. Further, said gradient is made zero by the circuit 10 by turning the source 6 off simultaneously with finishing of the irradiation and also, the circuit 9 is brought down for the B side and then, observation is carried out by operating an observation circuit 8. Here, the gradient of the magnetic field is turned into a function of the third degree making the central part of the sample of the starting point by setting up winding numbers of coils 5a, 5b, 5c, 5d suitably. Hereby, width of a zero part of the gradient of the magnetic field is extended and an SN ratio can be improved.

摘要： PROBLEM TO BE SOLVED: To enhance the resolution while stabilizing an NMR lock by holding a capillary fixed in place. SOLUTION: The NMR cell for measuring supercritical fluid is used in the NMR measurement of a supercritical fluid, with an inner plug inserted in the cell for preventing convection. The inner plug 4 for limiting the amount by which the supercritical fluid is sampled to inhibit convection and the capillary 5 with a deuterizing solvent sealed therein are integrated together and inserted in the cell whereby the capillary 5 is held fixed to the plug 4 and thus prevented from moving when the plug 4 is inserted in a pressure-resistant cell 3, so as to enhance resolution while stabilizing the NMR lock. Because this results in better of the insertion of the capillary 5, better reproducibility of resolution for every setting of a sample is provided and adjustment of the resolution is facilitated.

摘要： PROBLEM TO BE SOLVED: To apply strong electric field gradient to a sample without affecting the uniformity of the static magnetic field of an NMR device by an electrode by arranging a pair of electrodes formed by the thin film of diamagnetic metal in an NMR sample pipe and arbitrarily changing the distance between them. SOLUTION: Electrodes 9 and 10 made of a thin film such as platinum or gold that cannot be oxidized by diamagnetic and is strong against chemicals are mounted to bases 13 and 14 being mounted to nonmagnetic posts 7 and 8 consisting of a material with magnetic susceptibility substantially equal to that of a measurement sample 16. The pair of electrodes 9 and 10 is inserted into an NMR sample pipe 15 for allowing electrode surfaces to oppose each other at specific distance, the sample 16 is filled between them, a DC voltage with approximately several hundred volts is applied to the electrodes 9 and 10, and an electric field is applied to the sample 16. Since the distance between the electrodes 9 and 10 can be arbitrarily changed according to the size of the sample 16 and the strength of the required electric field, the variable range of the strength of the electric field becomes wide. Also, since the electrode 9 and 10 can be used while they are inserted into the normal NMR sample pipe 15, NMR measurement can be made by a general NMR probe.

摘要： PROBLEM TO BE SOLVED: To make exchangeable samples while keeping a cell in a set position and to make mixable a plurality of samplers under a high pressure. SOLUTION: An NMR cell for use in the NMR measurement of supercritical fluid has a capillary 4 with an end extended to near a bottom. A cell holder 3 provided with the connections of an inlet 1 and an outlet 2 has the capillary 4 connected to one of the connections to form a flow type cell 5. Samples can be exchanged without removal of the cell 5. The capillary 4 has a plug part integrated therewith which forms a fluid sump near the bottom within the cell 5 and closes the top. The fluid sump is communicated with the other of the connections via a clearance between the outer peripheral surface of the plug part and the inner peripheral surface of the cell to reduce a temperature gradient within a measuring sample system to inhibit convection. A pressurizer and a pressure regulator are connected respectively to the inlet and the outlet of the cell holder to enable the samples to be exchanged and mixed.

SOLUTION: This NMR cell for measuring supercritical fluid is an NMR used for measurement of supercritical fluid by providing an inner plug for preventing the convection inside. The inner plug 4 for limiting the sample quantity of a supercritical fluid so as to restrict the convention and a capillary 5 with a deuteride solvent sealed in it are integrated and put into the cell so that the capillary 5 is fixed to and held by the inner plug 4 and that the motion of the capillary 5 when putting the inner plug 4 into a pressure resistant cell 3 is prevented, and the resolution is thereby improved and the NMR lock is stabilized. Furthermore, since reproducibility of the insertion of the capillary 5 is improved, reproducibility of the resolution per sample setting is improved, and the resolution adjustment is facilitated.

摘要： PURPOSE:To securely perform lock-on operation in a short period by measuring a spectrum for control regarding a nucleus and setting the oscillation frequency of a locking oscillator according to the result. CONSTITUTION:A sample to be measured in a sample tube 2 and a control sample which contains a nucleus for magnetic field locking are irradiated with an impulsive high-frequency magnetic field which has the resonance frequency of the control nucleus from the oscillator 16 through a transmitting and receiving coil 4. An FID (free inductive decay) signal induced at the transmitting and receiving coil 4 after this pulse irradiation is sampled by an A-D converter 13 through a gate 19, a demodulator 21, and a switch 12, sent to a computer 14, and processed by Fourier transform to obtain a spectrum. The computer 14 performs peak search processing for the spectrum to find the accurate resonance frequency of the control nucleus and set the oscillation frequency of the oscillator 16 to it, thereby controlling the intensity of a polarizing magnetic field.
