Description

  The present invention relates to a preparation substrate used when deriving the elemental distribution of hair by fluorescent X-ray analysis, and further relates to a hair preparation in which hair is fixed to the preparation substrate and a hair fluorescent X-ray apparatus in which the hair preparation is arranged.

  Conventionally, various patent documents for performing physical condition diagnosis by performing elemental analysis of hair are known. In Japanese Patent No. 4065734 (Patent Document 1), calcium contained in the hair or root of hair is detected, and the precision is high when the content ratio of the detected calcium is higher than the content ratio of a healthy person. A physical condition inspection method serving as an inspection index is disclosed.

  Further, in Japanese Patent No. 462355 (Patent Document 2), the hair or body hair of the subject is subjected to elemental analysis, and the Ca concentration of the hair or body hair is a high Ca concentration level corresponding to Ca deficiency or Ca sufficiency, respectively. Alternatively, a method for detecting an abnormality in calcium metabolism by hair or body hair, which detects a calcium metabolism abnormality in the subject based on the comparison as compared with a low level, is disclosed.

In particular, both Patent Document 1 and Patent Document 2 use a synchrotron radiation facility such as SPRING-8 when performing elemental analysis of hair, and irradiate the hair with synchrotron radiation in the X-ray region as incident X-rays. The distribution of the elements contained in the hair is derived from the fluorescent X-rays generated from the hair. Since synchrotron radiation has an extremely high intensity, fluorescent X-ray analysis can be completed in a short time even for hair with a small size, and the element distribution can be easily derived.
However, the synchrotron radiation facility is a large-scale facility for joint use, and even if the facility can be used continuously, it is a short time, and it is not suitable for conducting a large number of hair tests on a commercial scale. It must be said that it is impossible.

Thus, an elemental analysis method for hair using a desktop fluorescent X-ray analyzer, which has been making rapid progress in recent years, has been developed. In the conventional patent No. 5372304, the signal ratio P _XRF (S) of the mineral contained in the hair derived from the subject to the sulfur contained in the hair is measured by a fluorescent X-ray analyzer, and the signal the ratio _{P XRF} (S), in order to calculate the elemental content _{M XRF} of the minerals contained in the hair, raw multiplying the transformation coefficients F to be used for this calculation, the signal ratio _{P XRF} and (S) A method for in-vivo element inspection, wherein a reference signal ratio P of the mineral contained in reference hair, which is hair derived from other than the subject, to the sulfur contained in the reference hair is determined by fluorescent X-ray analysis. _{0, XRF} and (S) were measured by inductively coupled plasma mass spectrometry, measuring the reference element content _{M 0, ICP} of the minerals contained in the reference hair, _{F = M 0, IC} / From P _0, the formula of _{XRF (S),} in vivo element inspecting method for calculating the transformation coefficient F is disclosed.

Japanese Patent No. 4065734 Japanese Patent No. 4612355 Japanese Patent No. 5372304

The technique of Patent Document 3 is an invention developed by the inventors of the present application, and the inventors of the present application performed fluorescent X-ray analysis of hair using the method shown in FIG. 6 of the present application.
The preparation substrate 101 is an acrylic resin substrate, and the hair 111 to be inspected is placed on the preparation substrate 101 in a contact state. Next, both ends of the hair 111 were adhered with adhesive tapes 112, 112, and a hair preparation 110 was prepared in which the hair 111 was stretched. Further, this hair 111 is irradiated with incident X-rays 121 from an X-ray source 120 at a low angle, the incident X-rays 121 are totally reflected by the preparation substrate 101, and the reflected X-rays 125 are also reflected and emitted at a low angle. . The fluorescent X-ray 123 was emitted upward from the hair 111, and this fluorescent X-ray 123 was detected by the detector 130, and the fluorescent X-ray analysis of the hair 111 was performed.

In repeating this research, the inventors of the present invention mixed in the elemental distribution of hair obtained by fluorescent X-ray analysis with an impurity element that should not be originally contained in hair, Even found the fact that the peak value is abnormally high. In pursuit of this cause, when fixing the hair to the acrylic preparation substrate, the hair and the preparation substrate rub against each other and the hair is charged and stays on the surface of the impurity element and the preparation substrate floating in the air. It has been confirmed that the impurity elements to be electrostatically adsorbed on the hair and that these impurity elements are mixed in the element distribution. In addition, even when total reflection X-ray fluorescence analysis was performed, it was found that the impurity elements increased as a result of the slight mixing of fluorescent X-rays from the preparation substrate itself.
When a fluorescent X-ray analyzer that is not a total reflection type is used, incident X-rays pass through the preparation substrate or enter and reflect the preparation substrate, so a large amount of impurity fluorescent X-rays are generated from the preparation substrate itself. As a result, a large amount of impurity fluorescent X-rays are included in the fluorescent X-rays from the hair, and as a result, a large amount of impurity elements are mixed in the element distribution, causing an error in the determination of the accurate element distribution of the hair. It was.

  Accordingly, a first object of the present invention is to provide a preparation substrate that eliminates frictional charging due to mutual friction between the hair and the preparation substrate and that does not generate fluorescent X-rays from the preparation substrate itself, and hair using this preparation substrate. It is to provide a preparation. The second object of the present invention is to provide a preparation substrate that facilitates the height adjustment and position adjustment of hair as a sample, the incident angle adjustment of incident X-rays, and the like. A third object of the present invention is to provide a hair fluorescent X-ray apparatus with high elemental analysis accuracy by arranging the hair preparation in the fluorescent X-ray apparatus.

  As a result of diligent research, the present inventors have come up with a technique that eliminates the frictional contact between the hair and the preparation substrate in order to prevent contamination by impurity elements. Ideally, if the hair is suspended in air and X-rays are irradiated to the suspended hair, frictional charging will not occur, and there should be no fluorescent X-rays from the preparation substrate itself. A state close to such a floating arrangement may be realized. That is, if a hole is made in the preparation substrate, the hair is passed across the hole, and both ends of the hair are fixed to the peripheral portion of the hole with an adhesive tape or the like, the hair and the preparation substrate do not rub against each other. Therefore, the noise of the impurity element due to electrostatic adsorption can be removed. Moreover, since the hair region irradiated with the incident X-ray has a hole, the incident X-ray is not irradiated onto the preparation substrate. Therefore, the fluorescent X-rays from the preparation substrate itself can be eliminated.

  The present invention has been made to solve the above problems, and a first embodiment of the present invention is a preparation substrate used for fluorescent X-ray analysis of hair, and the hair is stretched on the preparation substrate. It is a preparation substrate which opens a hole and fixes both ends of the hair to the peripheral portion surrounding the hole.

  The second aspect of the present invention is a preparation substrate in which the preparation substrate is made of a resin substrate.

  According to a third aspect of the present invention, the preparation substrate according to the first aspect or the second aspect, the hair stretched across the hole, and both ends of the hair are fixed to a peripheral portion surrounding the hole. A hair preparation composed of fixing means.

  According to a fourth aspect of the present invention, the hair preparation described in the third aspect is disposed, and an X-ray source that irradiates incident X-rays to the hair of the hair preparation and fluorescent X-rays emitted from the hair are detected. It is a hair fluorescent X-ray apparatus having at least a detector.

According to the first aspect of the present invention, there is provided a preparation substrate used for fluorescent X-ray analysis of hair, wherein a hole for stretching the hair is opened in the preparation substrate, and both ends of the hair are surrounded by a peripheral portion surrounding the hole. Can be provided.
Since the prepared substrate has a hole, if the sample hair is placed over the hole and both ends of the hair are fixed to the peripheral edge, friction does not occur between the hair and the hole. Accordingly, since the hair is not frictionally charged, the impurity element in the air is not electrostatically adsorbed, and the impurity element is not mixed as noise even when the fluorescent X-ray analysis is performed. In addition, even if incident X-rays are applied to the hair, there are only holes on the lower side of the hair, so fluorescent X-rays from the preparation substrate are not generated, and fluorescent X-rays from the preparation substrate may be mixed as noise. Therefore, it is possible to accurately and accurately derive the hair element distribution.
Further, since the preparation substrate has a hole, the front can be seen through the hole regardless of whether the preparation substrate is viewed from above or from below, and the preparation substrate can be easily adjusted up and down. Further, since the hair is suspended over the hole, there is an advantage that it is easy to adjust the incident angle of incident X-rays applied to the hair. Overall, X-ray adjustment efficiency is improved.
As for the shape of the hole, various shapes such as a round shape, a square shape, and a triangular shape can be adopted, but a circular shape having the highest rotational symmetry is most preferable.

According to the 2nd form of this invention, the said preparation substrate is a preparation substrate comprised from a resin substrate. When the substrate is molded from the resin, since the resin has flexibility, there is little risk that the prepared substrate is cracked or chipped while the hole is being formed, and there is an advantage that the hole can be safely opened.
Moreover, a transparent resin substrate is effective among the resin substrates. Since the front and rear can be seen through the transparent resin substrate, there is an advantage that position adjustment and incident X-ray incident angle adjustment can be easily performed. Transparent resins include polyethylene, polypropylene, polyethylene terephthalate, vinyl chloride, polystyrene, ABS resin, acrylic, methclear, polyamide, polycapade, tetrafluoroethylene, ethylene acid bicopolymer, finol resin, melamine, unsaturated polyester, epoxy, etc. However, other transparent resins can be used.

According to the 3rd form of this invention, the preparation board as described in the 1st form or the 2nd form, the hair spanned across the said hole, and the peripheral part which surrounds the said hole at the both ends of the said hair A hair preparation comprising fixing means for fixing to the hair can be provided.
In order to fix the hair as a sample to the preparation substrate of the present invention, first, one end of the hair is fixed to the peripheral portion surrounding the hole of the preparation substrate. An adhesive tape is effective as the fixing means, but there are various fixing means such as an instantaneous adhesive or hooking on a slit cut in the peripheral edge. When one end is fixed, the other end is fixed to the peripheral edge in a state where the hair is tensioned with a pin (stretched state). For fixing the other end, various fixing means such as an adhesive tape, an instantaneous adhesive, and a hook can be used.
As described above, the hair preparation in which the sample hair is stretched on the preparation substrate of the present invention is effective in the fluorescent X-ray analysis. When the sample hair is mailed from all over the country, there is a risk that the hair itself disappears in the middle because it is fine. Therefore, if the subject creates a hair preparation with his hair attached to the preparation substrate and mails the hair preparation to the analysis organization, the risk of the hair sample disappearing is extremely low. Since the hair preparation has a certain size, it does not easily disappear naturally, so it is safe. In addition, there is an advantage that the laboratories for preparing the hair preparation can be saved and the sent hair preparation can be immediately subjected to fluorescent X-ray analysis.

According to the fourth aspect of the present invention, the hair preparation described in the third aspect is arranged, an X-ray source that irradiates the hair of the hair preparation with incident X-rays, and fluorescent X-rays emitted from the hair. A hair fluorescent X-ray apparatus having at least a detector for detection can be provided.
As described above, in the hair preparation of the present invention, a hole is opened in the lower part of the hair that has been stretched, and the incident X-ray may be applied to the hair from above, and the transmitted X-ray may pass through the hole. In addition, incident X-rays may pass through the hole from below and irradiate the hair, and transmitted X-rays may escape upward, and the hair is irradiated at a very low angle with respect to the substrate, and the transmitted X-rays are reflected X-rays. As such, it may be reflected at an extremely low angle, or may be incident on the hair at an acute angle. In addition, there is a hole in the lower part of the hair, and the incident angle of incident X-rays can be adjusted while visually recognizing this hole, making it easy to adjust the height and position of the preparation substrate. It is what has.

FIG. 6 shows a total reflection type fluorescent X-ray apparatus in which hair is attached to a conventional holeless preparation substrate, and incident X-rays are irradiated to the hair at an ultra-low angle to detect fluorescent X-rays emitted upward. It is a schematic explanatory drawing.

Hereinafter, embodiments of a preparation substrate, a hair preparation, and a hair fluorescent X-ray apparatus according to the present invention will be described in detail with reference to the drawings.
FIG. 1 is a perspective view showing a state where holes of various shapes are opened in a preparation substrate according to the present invention. Although the shape of a hole is not specifically limited, (1A)-(1C) are shown as a typical example below. Specifically, (1A) is a perspective view of the prepared substrate 1 having a circular hole 3 opened in the center. A peripheral edge 5 is formed surrounding the hole 3, and both ends of the hair described later are fixed to the peripheral edge 5. (1B) is a perspective view of the prepared substrate 1 having a square hole 3 opened at the center. A peripheral edge 5 is formed surrounding the hole 3, and both ends of the hair described later are fixed to the peripheral edge 5. (1C) is a perspective view of the prepared substrate 1 having a triangular hole 3 opened in the center. A peripheral edge 5 is formed surrounding the hole 3, and both ends of the hair described later are fixed to the peripheral edge 5.

  The material of the preparation substrate 1 is not particularly limited, but a material that does not break the preparation substrate when the hole 3 is opened or does not chip around the opened hole is selected. A transparent substrate is recommended as the preparation substrate 1. With a transparent substrate, the front and rear states can be confirmed through the substrate, the height and position of the slide substrate can be easily adjusted, and the incident X-ray incident direction can also be adjusted through the adjustment. . Furthermore, a material that is difficult and / or free from frictional charging is desired, and a metal substrate or a conductive resin substrate is preferable. Accordingly, the inexpensive resin substrate is a flexible resin substrate, a transparent resin substrate is preferable, and a conductive transparent resin substrate is the best. In an inorganic substrate such as glass or ceramic, holes are formed by an opening method without cracks. The metal substrate does not crack when the hole is opened, and is conductive, but has an opaque weakness.

  As the resin substrate, all existing resins are used. In particular, transparent resins include polyethylene, polypropylene, polyethylene terephthalate, vinyl chloride, polystyrene, ABS resin, acrylic, metaclear, polyamide, polycapade, tetrafluoroethylene, ethylene acid bicopolymer, finol resin, melamine, unsaturated polyester, epoxy Other transparent resins can also be used. As the conductive resin, polythiophene resin, polyacetylene resin, polyaniline resin, or polypyrrole resin can be used.

FIG. 2 is a perspective view of various hair preparations in which hair is stretched and fixed in the holes of the preparation substrate according to the present invention.
As typical examples, (1A) to (1C) are shown below. Specifically, (1A) shows a hair preparation 10 using a preparation substrate 1 having a round hole 3 in the center, and the peripheral portions 5 and 5 are fixed by fixing means 12 having both ends of the hair 11 made of adhesive tape. It is fixed in tension. (1B) shows a hair preparation 10 using a preparation substrate 1 having a square hole 3 opened in the center, and both ends of the hair 11 are stretched around the peripheral portions 5 and 5 by fixing means 12 made of instantaneous adhesive. It is fixed. (1C) shows a hair preparation 10 using a preparation substrate 1 having a triangular hole 3 opened in the center, and both ends of the hair 11 are stretched at the peripheral portions 5 and 5 by fixing means 12 made of staples of U-shaped needles. It is fixed in the installed state. Therefore, various fixing means 12 exist, and fixing means other than those described above are also included in the present invention.
As described above, both ends of the hair 11 are fixed at the peripheral portions 5 and 5 by the fixing means 12, and the hair 11 is stretched around the pin 3 in a state of being stretched over the hole 3. Accordingly, the hair 11 is not in contact with the preparation substrate 1 except for the peripheral portion 5, and the hair 11 can be physically avoided from being frictionally charged by rubbing. In addition, since the incident X-rays can be taken in and out through the hole 3, the fluorescent X-rays from the preparation substrate 1 are blocked, the fluorescent X-rays other than the hair 11 are blocked, and the impurity element is not included in the element distribution. Accurate and precise element distribution can be derived.

FIG. 3 is a schematic explanatory diagram of a hair fluorescent X-ray apparatus that detects X-rays emitted upward by irradiating the hair of the hair preparation according to the present invention with incident X-rays at a low angle.
The hair fluorescent X-ray device 40 according to the first embodiment of the present invention is radiated from the hair 11, the X-ray source 20 that irradiates the hair 11 with the incident X-ray 21, and the hair 11. It comprises a detector 30 that detects by making fluorescent X-rays 23 incident.
In particular, the fluorescent X-ray apparatus of the first embodiment is generally called a total reflection type fluorescent X-ray apparatus. However, when the prepared preparation substrate 1 having no holes is used, it enters the preparation substrate 1 at a low angle. Then, since the incident X-rays 21 are totally reflected by the substrate 1, the fluorescent X-rays from the preparation substrate 1 have a characteristic that is not easily emitted. However, since the hair 11 and the preparation substrate 1 are in contact with each other, the fluorescent X-rays from the substrate 1 cannot be completely blocked, and some fluorescent X-rays are mixed from the preparation substrate 1 as noise. Yes.
On the other hand, in the hair fluorescent X-ray device 40 of the present embodiment, the incident angle of the incident X-ray 21 is set to a very low angle, but the incident X-ray 21 is reflected by the hair 11 and becomes the reflected X-ray 25, Since it only passes through the hole 3, it does not enter the preparation substrate 1, and no fluorescent X-rays are generated from the preparation substrate 1. Accordingly, only the fluorescent X-rays from the hair 11 are generated, and only the fluorescent X-rays 23 enter the detector 30. Therefore, the elemental distribution of the hair 11 obtained by analyzing the fluorescent X-rays 23 contains an impurity element. The exact element distribution in the hair 11 can be derived.
Further, when the fluorescent X-ray apparatus is initially adjusted, the internal structure can be confirmed through the hole 3, so that the incident angle of the incident X-ray 21 and the height and position of the hair preparation 10 can be easily adjusted. Have Since the hair 11 is not in contact with the hole 3, there is no frictional charge, and the hair 11 does not electrostatically adsorb impurity elements in the air. Therefore, if the hair fluorescent X-ray apparatus 40 according to the present embodiment is used, the fluorescent X-ray apparatus 40 in which noise is almost completely blocked can be provided, and the element distribution of the hair 11 can be derived accurately and precisely.

FIG. 4 is a schematic explanatory view of a hair fluorescent X-ray apparatus that irradiates the hair of the hair preparation according to the present invention with incident X-rays at a high angle and detects fluorescent X-rays emitted upward at a high angle. .
The hair fluorescent X-ray apparatus 40 according to the second embodiment of the present invention shown in the figure is a hair preparation 10 arranged in the apparatus, an X-ray source 20 that irradiates the hair 11 with incident X-rays 21 at a high angle, The detector 30 is configured to detect the fluorescent X-rays 23 emitted from the hair 11 at a high angle.
In the apparatus of the second embodiment, when the preparation substrate 1 having no holes is used, it enters the preparation substrate 1 at a high angle. Therefore, since the incident X-rays 21 are transmitted through the substrate 1, a large amount of fluorescent X is emitted from the preparation substrate 1. It has a weak point where the line is radiated. Therefore, since a large amount of fluorescent X-rays from the preparation substrate without holes is mixed as noise, the elemental analysis of hair as a fine sample has a weakness that is buried in the noise.
In contrast, since the hair fluorescent X-ray apparatus 40 of the present embodiment uses a substrate with holes, even if the incident angle of the incident X-ray 21 is set to a high angle and the incident X-ray 21 passes through the hair 11, Since the incident X-ray 21 only passes through the hole 3, it does not enter the preparation substrate 1, and no fluorescent X-rays are generated from the preparation substrate 1. Accordingly, only the fluorescent X-rays from the hair 11 are generated, and only the fluorescent X-rays 23 are incident on the detector 30. Therefore, there is no impurity element in the element distribution of the hair 11 obtained by analyzing the fluorescent X-rays 23. It is not contained, and an accurate element distribution in the hair 11 can be derived.
Similarly to the first embodiment, when the fluorescent X-ray apparatus is initially adjusted, the internal structure can be confirmed through the hole 3, so that the incident angle of the incident X-ray 21 and the height of the hair preparation 10 can be adjusted. There is an advantage that the position can be easily adjusted. Since the hair 11 is not in contact with the hole 3, there is no frictional charge, and the hair 11 does not electrostatically adsorb impurity elements in the air. Therefore, if the hair fluorescent X-ray apparatus 40 of this embodiment is used, the fluorescent X-ray apparatus 40 in which noise is almost completely blocked can be provided, and the element distribution of the hair 11 can be derived accurately and precisely.

FIG. 5 shows an outline of a hair fluorescent X-ray apparatus that detects X-ray fluorescence radiated downward at a high angle by irradiating incident X-rays through the hole from below with respect to the hair of the hair preparation according to the present invention. It is explanatory drawing.
The hair fluorescent X-ray device 40 according to the third embodiment of the present invention shown in the figure is a hair preparation 10 arranged in the device, and an X-ray source that irradiates the hair 11 with incident X-rays 21 almost vertically from below. 20 and a detector 30 that detects the fluorescent X-rays 23 radiated from the hair 11 downward at a high angle.
In the apparatus of the third embodiment, when the preparation substrate 1 having no holes is used, since the incident X-ray 21 enters the preparation substrate 1 vertically upward, the incident X-ray 21 passes through the substrate 1. There is a weak point where a large amount of fluorescent X-rays is emitted from 1. That is, a large amount of fluorescent X-rays from the preparation substrate without holes is emitted downward as noise and mixed into the fluorescent X-rays from the hair 11, and the elemental analysis of the hair, which is a fine sample, has a weakness that is buried in the noise. .
On the other hand, since the hair fluorescent X-ray apparatus 40 of this embodiment uses a substrate with holes, even if the incident X-rays 21 are incident almost vertically upward and pass through the hair 11, the incident X-rays 21 pass through the holes 3. Since it is only transmitted, it does not enter the preparation substrate 1 and no fluorescent X-rays are generated from the preparation substrate 1. Accordingly, only the fluorescent X-rays from the hair 11 are generated, and only the fluorescent X-rays 23 are incident on the detector 30. Therefore, there is no impurity element in the element distribution of the hair 11 obtained by analyzing the fluorescent X-rays 23. It is not contained, and an accurate element distribution in the hair 11 can be derived.
Further, as in the first embodiment, when the fluorescent X-ray apparatus is initially adjusted, the internal structure can be confirmed through the hole 3, so that the incident angle of the incident X-ray 21 and the height of the hair preparation 10 can be adjusted. There is an advantage that the position can be easily adjusted. Since the hair 11 is not in contact with the hole 3, there is no frictional charge, and the hair 11 does not electrostatically adsorb impurity elements in the air. Therefore, if the hair fluorescent X-ray apparatus 40 of this embodiment is used, the fluorescent X-ray apparatus 40 in which noise is almost completely blocked can be provided, and the element distribution of the hair 11 can be derived accurately and precisely.

  Using the perforated preparation substrate 1 of the present invention, the back surface of the hair 11 is only the hole 3 regardless of the arrangement of the incident direction of the incident X-ray 21 and the emission direction of the fluorescent X-ray 23. There is an advantage that the fluorescent X-rays from the preparation substrate 1 are not almost completely generated, and only the fluorescent X-rays from the hair 11 can be incident on the detector 30, and the element distribution of the hair 11 can be measured accurately and precisely. Have

  The present invention is not limited to the above-described embodiments and modifications, and includes various modifications and design changes within the technical scope without departing from the technical idea of the present invention. Needless to say.

  As described above in detail, if the preparation substrate with holes, hair preparation and hair fluorescent X-ray apparatus according to the present invention are used, an accurate and precise element distribution of hair can be derived, and the conventional preparation without holes is provided. It is now possible to derive an element distribution that is far superior in accuracy and precision than the elemental distribution of hair derived using a substrate.
