Sample analysis system, sample analysis device, and sample analysis method

Abstract

The invention provides a sample analysis system, a sample analysis device, and a sample analysis method. A substance information DB (50) stores information of a plurality of substances that have beencreated in advance as a database. The associated substance name DB (60) stores the names of a plurality of associated substances included in a predetermined type (asbestos, clay minerals, and the like). A processing device (30) is configured so as to extract, from the information of the plurality of substances stored in the substance information DB (50), information of a substance having the nameof the associated substance stored in the associated substance name DB (60), and to perform qualitative analysis of the sample by comparing the measurement result of an X-ray diffraction device (10) with the extracted substance information.

Description

technical field [0001] The present disclosure relates to a sample analysis system, a sample analysis device, and a sample analysis method. Background technique [0002] Among the X-ray diffraction (XRD: X-Ray Diffraction) methods that irradiate a sample with X-rays and analyze the constituent elements of the sample by using the X-ray diffraction phenomenon, there is known a method that treats a polycrystal as a sample. Powder X-ray Diffraction. In the qualitative analysis of powder X-ray diffraction, the substance contained in the sample is identified by comparing the diffraction pattern actually measured by irradiating the sample with X-rays and the diffraction pattern of the known substance prepared in advance as a database. Identification. [0003] Specifically, in the diffraction pattern of a sample whose abscissa is the diffraction angle 2θ and the ordinate is the diffraction intensity I, Bragging (2d×sinθ=nλ, d: spacing between grating surfaces, λ: incident X The wa...

Problems solved by technology

[0008] First, for example, in the case of using ICDD’s PDF-4+ as a database, there are more than 400,000 pieces of information on various substances registered, and there is a possibility that it may not be possible to obtain the expected information even if it is searched using the above-mentioned Hanawat method search results for

[0009] In addition, in the PDF of ICDD, groups classified by types of minerals, organic substances, and inorganic substances can be searched for, but even so, for example, the There are also more than 40,000 pieces of substance information, and there is a possibility that the expected search results may not be obtained

[0010] Second, although it is also possible to create a database of diffraction patterns by yourself after actually measuring known substances, and use this database for searching, in order to make a useful database, it is necessary to actually measure many (for example, hundreds of) known substances and It takes a lot of work to create a database of diffraction patterns for each substance

Although this method has a high probability of obtaining the expected search results, it is necessary to search for a large number (for example, hundreds of types) of identifiers of substance information and register them in the list. Register substances into the list
