Abstract

PURPOSE:To enable the maintenance of a constant density of proton for a long term by diffusing silicate material into thermosetting resin. CONSTITUTION:The textile fabric, knitted fabric or nonwoven fabric of long glass fibers 1 is distributed in the shape of a mat in thermosetting resin 2. As silicate material similar to the fibers 1, short glass fibers 3 and the powder of glass fibers are used other than the fibers 1. A variety of test plates for NMR having different density of proton from each other can be formed according to the state of diffusion of each material.

Description

[Detailed Description of the Invention] [Technical Field of the Invention] This invention belongs to the technical field of nuclear magnetic resonance apparatus (hereinafter sometimes abbreviated as single KmR).

[Development @O technical background and its problems]

By applying the NMROjl principle, which is used as a scientific measuring instrument, it is possible to directly detect pro)/1llf in water, which is a major component of living tissues, in a non-invasive manner. Since normal cells and cancer cells in living tissues have different proton concentrations, NMR can be used for cancer screening. However, since there is only a small number of protons between normal cells and cancer cells, the proton concentration in both lipids remains stable.
Larger #i to be evaluated with R, 2 appropriate as a standard number
A test plate for m is required.

Conventionally, a water-containing substance such as soft gelatin, a water-containing sponge, or a hydrophilic polymer, which is suitably formed into an O-shape, has been used as a test plate for m. However, these conventional test plates for ships are greatly affected by the temperature of 11 degrees Celsius, and there is a high risk of deformation and deterioration due to the presence of moisture.
Therefore, with these conventional test plates for MDm, it is difficult to maintain a constant proton level at one time for a long period of time, for example, 10 parts.

[Purpose of the invention]

The present invention has been made in consideration of the above circumstances, and the object of the present invention is to provide a test plate for Mυ that can maintain a constant concentration of protons over a long period of time.

[Summary of the invention]

The outline of the present invention for achieving the above object is characterized in that a silicic acid substance is dispersed in a thermosetting resin.

[Embodiments of the invention]

FIG. 1, FIG. 2, and FIG. 6 are explanatory diagrams showing embodiments of the present invention.

NMR test plate mat shape according to this invention,
7.It is characterized by being made by dispersing either a lake-like or powder-like silicic acid substance in a thermosetting resin.

As the silicic acid material, for example, glass is preferable.

Examples of thermosetting resins include unsaturated polyester,
Epoxy resins, phenol resins, etc. are preferred. Dispersion of the silicic acid substance into the thermosetting resin can be achieved by, for example, distributing woven, knitted or nonwoven fabrics of long fiber glass fibers 1 in the thermosetting resin 2 in the form of a mat, as shown in FIG. (matte-like dispersion), distributing the short glass fibers 6 in flakes in the thermosetting resin 112 (flake-like dispersion), distributing glass fiber powder 4, for example, in the thermosetting resin 2 (powdered dispersion). Dispersing in various states in this way means that various NMR molecules with different proton concentrations are produced depending on the dispersion state.
This is because it can be used as a test plate.

(9) The proton concentration differs depending on the state of dispersion because the cross-sectional area of the fracture cross section of the silicic acid material differs depending on the state, so the amount of H+ or 0ft) bonded differs depending on the fracture valence. This is because it will happen.

As described above, when a silicic acid substance is dissolved into a thermosetting resin, r+ωr, which is bonded to the fracture valence of the silicic acid substance by the fracture valence, is incorporated in a thermosetting state and is isolated from the outside air. Therefore, the proton concentration in the NMR test plate according to the present invention can be maintained constant over a long period of time.

Although one embodiment of the present invention has been described above in detail, the present invention is not limited to the above embodiment, and can be implemented with various modifications within the scope of the gist of the invention.

〔Effect of the invention〕

According to the present invention, although the structure is simple, the proton concentration is maintained constant over a long period of time, and a test plate for iNMR can be provided.

First, since the proton concentration can be changed depending on the dispersion IIK of the silicic acid material, N with various proton concentrations can be used.
A test plate for MR can be provided.
