Description

The present invention relates to a particle size display device, a particle size display method, and a particle size display system, and more particularly to a particle size display device, a particle size display method, and a particle size display system that display particle size analysis results in a graph format.

In recent years, products using fine particles have been manufactured in the industrial field, the medical field, the food field, and the like. When manufacturing a product using fine particles, it is necessary to inspect the particle size of the fine particles in the manufactured product. Therefore, conventionally, an apparatus for measuring the particle size of fine particles is known (see, for example, Patent Document 1 and Patent Document 2).

In Patent Document 1, the particle size of the ceramic powder when producing the ceramic powder for a dielectric is measured by using an image analysis method. The image analysis method is a method in which a part of an object to be measured is applied to a substrate or the like, an image is taken, and the particle size of each particle is measured from the taken image. In Patent Document 1, the particle size is measured by acquiring an image of an object to be measured (ceramic powder) using a scanning electron microscope (hereinafter referred to as SEM).

Further, in Patent Document 2, the particle size of the noble metal particles is measured by using a dynamic light scattering method (hereinafter referred to as DLS) at the time of manufacturing the catalyst for purifying exhaust gas using the noble metal particles. DLS is a method of measuring the particle size based on the fluctuation of scattered light caused by the Brownian motion of the particles in the solution.

Japanese Unexamined Patent Publication No. 2006-273708 JP-A-2017-1770114

Here, the measurement of the particle size using SEM as described in Patent Document 1 is to measure the particle size of the particles appearing in the image of a part of the object to be measured, and the obtained particle size is obtained. Cannot be determined whether or not can be used as the particle size of the entire object to be measured. Further, in the measurement of the particle size using DLS as described in Patent Document 2, it is possible to measure the particle size of the entire object to be measured, but the object to be measured is aggregated in the solution. In some cases, the individual particle size cannot be measured in order to measure the size of the agglomerated mass of particles. Therefore, in order to obtain an accurate particle size of the object to be measured, for example, particle size distribution measurement using SEM as described in Patent Document 1 and DLS as described in Patent Document 2 are performed. It is necessary to analyze the measurement results obtained by using multiple measurement methods such as the particle size measurement used.

The measurement results by the method were analyzed using table calculation software and the like. Specifically, the particle size results were analyzed by creating a graph of the particle size results measured by a plurality of particle size measuring devices using spreadsheet software or the like.

However, when analyzing particle size results using a graph created using spreadsheet software, if you want to change the combination of multiple particle size measuring devices, you will have to recreate the graph.

For example, even when one particle size measuring device 2 is used, the standard of the obtained particle size result 4 may be different if the measurement conditions and the like are different. When the criteria of the obtained particle size result 4 are different, it is necessary to standardize the particle size result 4 when displaying a plurality of particle size results 4 on the same screen.

The item may be further provided, and the two selected particle size results 4 may be superimposed and displayed on the same screen from the correlation diagram 16 of the average particle size 10. Specifically, the control unit 38 displays the second display area 12 on which the graph of the particle size result 4 as shown in FIG. 18 is displayed from the correlation FIG. 16 having the average particle size 10 as shown in FIG. It may be configured to be displayed in 3.

In the example shown in FIG. 17, for convenience, the difference in the particle size measuring device 2 that measured the particle size result 4 as shown in the legend L4 of the particle size measuring device is displayed by the difference in the line type of the graph. .. Specifically, in the example shown in FIG. 17, each particle size result 4 of the particle size result 4 measured by the first particle size measuring device 2a and the third particle size measuring device 2c is shown as a solid line L4a and two, respectively. It is indicated by the dotted line L4b.

Further, in the second and third embodiments, the particle size distribution standardization result 13 in which the control unit 38 standardizes the particle size result 4 measured by the third particle size measuring device 2c (DLS) is displayed. Although an example of the configuration in which the second display area 12 is displayed on the display unit 3 is shown, the present invention is not limited to this. For example, as shown in FIG. 19A, the control unit 38 includes a first particle size measuring device 2a (SEM), a second particle size measuring device 2b (AFM), and a fourth particle size measuring device 2d (ICP-MS). ), The particle size distribution standardization result 19 standardized by the volume standard (frequency (%)) may be displayed on the display unit 3. In the particle size distribution standardization result 19 shown in FIG. 18A, the horizontal axis is the particle size (nm) and the vertical axis is the frequency (%). In FIG. 19A, for convenience, each particle size result 4 is shown in the line of the graph in the same manner as the graph of the first particle size distribution comparison result 14 shown in FIG. 11B in the second embodiment. It is shown by the difference in type. Specifically, as shown in the legend L5 of the particle size measuring device, each particle size result 4 of the particle size result 4 measured by the first particle size measuring device 2a to the fourth particle size measuring device 2d is shown by a solid line. It is indicated by L5a, a broken line L5b, a two-point chain line L5d, and a one-point chain line L5c.

When the particle size result 4 is standardized based on the volume (frequency (%)), the control unit 38 divides the measured number of particles of each particle size in the particle size result 4 by the total number of measured particles. Therefore, it may be configured to be standardized. The example shown in FIG. 19B is an example of standardizing the particle size result 4 measured by the first particle size measuring device 2a (SEM). As shown in Table 20 of FIG. 19B, the control unit 38 standardizes the measured number of particles of each particle size by dividing by the total number of measured particles (for example, 93).
