In order to create a glass speed of the appropriate shape, the total h'i of the sample and melting agent must be approximately 47 or higher, and for samples such as J-J, a pattern of several tens of mym is required. When the temperature increases, the rate of dissection by the melting agent increases by 1·d, and the fluorescent X-ray intensity becomes weaker.

<A difficult 1st class problem arises. Although the former problem has been solved by X expansion (a device capable of increasing W and thickening has been developed) and especially by lri'T, the latter problem remains. However, the problems with the latter are as follows. In general, in constant analysis using fluorescent X-rays, when comparing the spectra of the standard sample and the analysis sample, it is V (therefore performed), so the standard value (analytical value or content of the standard component) is known. A standard sample is essential. Therefore, in order to use it as a standard sample, L;; quasi (ll
′! 6.Chemical analysis is essential to determine. In order to analyze each element, it is natural to prepare samples from many mice. However, in a sample as mentioned above, which is only a few tens of liters, it is impossible to obtain standard values for each element. I can't decide. For this reason, 1. IC1 prototype was synthesized to create a standard sample. One possible method for analysis is to obtain a detection line between the concentration of the element to be measured (or its compound) and the spectral line intensity.
value, it is k (also a trace amount of reagent h)
゛V (It becomes necessary to prepare a standard sample using a pestle, but this is extremely difficult, and the scale has a large error.Only an expert with a level of 3011I!1' can collect it with a pestle) When trying to analyze a sample, the elements to be measured must be sampled with a pestle and elbow directly.
When the autonomy rate of the element to be measured is 01%, the reagent is 0.

Wk It is necessary to pestle accurately, and it is extremely difficult like this)′ν
If you weigh the tail, the balance i-error will increase and accurate analysis will not be possible. Furthermore, when using the same type of standard sample as the sample to be analyzed using the 1,1 method, it is necessary to prepare a large number of standard samples for each type of sample. It's inconvenient. For the purpose of the present invention, such problems of the prior art are solved! iE also for the '1'h sample.

] - To provide. In the method of the present invention, a reagent containing a target substance of 1illl and 1illl is combined with a target content ratio r(1./(weighed ml and mixed). The reagents and the melting agent are heated in a homogeneous glass-like bathtub and then cooled to a solid paste, followed by pulverizing the solidified product.The method of the present invention In VC, the element to be measured, t, is any element targeted by the K4A analysis method. - Any material can be used as long as the all-rhodium crucible is not loose. Also, as the melting agent, any glass-forming substance that forms glass by heating can be used. However, among them, generally adopted σi and one'rNa
, l3407. Li, B, O, etc. are suitable. These reagents and melting agents are weighed and mixed to a target content, and then heated until a glassy molten metal is obtained. In this weighing process, the distribution of the reagent and melting agent between the punches is determined so as to be within the measurement overlapping range of the punching device that can ensure sufficient viscosity. When using a glass bead making device with a stirring mechanism, make sure to mix thoroughly [
You can simply add 10,000 to the other. Regarding melting, the reagent and melting agent are placed in a platinum crucible or the like and heated and melted using an appropriate heating means such as an electric furnace or a gas burner. The heating temperature is preferably slightly higher than the melting point of the melting agent. Reagent and 1. i! 11'N1. ^11 After the proboscis becomes a glass-like melt, this 7L (r-cooled and solidified ζ 1) Next, this solidified material is pulverized. The primary sample is prepared using 17rL of the reagent. and the 111th tithe of the melting agent J is positive (1'(+), so using ζ-re, the Yusho quasi-sample becomes extremely 1-ton & * Ii4:. That is, 1-6 self's 16' Test 1 - 5 Create fl with elements &(r-') of 111 different soils, and from among the primary samples of this 1 et al. Pestle: 1.

becomes Ichicho Noh. In this way, we created appropriate primary samples for each reagent VC and C target #question, and the total number of reagents was 3014.
Mixing of the melting agent (mixing the primary samples of each yuzu so that 4 becomes 4F and adding glass speed with an excessive content range) 1. One quasi-sample item can be prepared.At this time, 30?
θ, but add the melting agent ν or the missing amount [2 to 1tf]
If it is set to 4r, the operation is only f+iM. Furthermore, the above numerical values are just examples, and the present invention is not limited to these numerical values.
1. Since the standard sample group prepared in 1. has good balance accuracy,
Fluorescent X-ray intensity and standard 1lli (total reagent synthesis 3) for each element
There is a very good correlation between the concentration of the target element reagent in 0.0 l, and a good calibration curve can be obtained. In each case, if you analyze all other standard samples such as slag and flux in the above-mentioned inspection, you will notice if there is a deviation in the two analytical values U. The inventor investigated the cause of this problem and discovered that because the bath is melted at a high temperature of, for example, 1000 to 1200°C, the primary It was not recognized that this was due to a change in the ratio of the test mulberry pattern to the melting agent growth of the sample, that is, the content of the target element. If it is about the loss of melting agent on ignition, it may be 17 in the same lot, but if the melting temperature and time are constant, the loss is almost ->t
Therefore, the problem is tYh, or the ignition reduction h1- of the reagent or pure I

If you VC like this, the burning decrease i11. σ) shadow f#, such as purity, etc., can be analyzed accurately at t1. Example reagent stand @ 30 mf, standard sample prepared with 4 volts of melting agent I11 Test of S i O, determined from all phases) Ii
Figure 1 shows the relationship between the standard value of S i O, and the fluorescence 0 From Figure 1, the method of the present invention tC, therefore, the standard sample VC group (the calibration curve is very good, and other existing standard samples also work well for this test). σ). It is recognized that accurate analysis can be performed. In addition, Fig. 1 shows the Sin when synthesized by directly weighing the reagents. The relationship between the strong fluorescent X-rays and W is also 7°.
From now on, it is confirmed that the standard sample sample ↓ prepared from No. 1) according to the method of the present invention has an accurate concentration. As described above, according to the present invention, multi-element analysis can be easily carried out even with seven test tubes on the order of η, which was conventionally difficult and impossible. -Also, for each type of sample, a large number of standard reagents [(I:fx<, even if the reagents are fully synthesized standard reagents)
Because it can be done easily, the analysis work is easy.
