- the electromagnetic wave as a probe has to be transmitted not only through the gap arrangement structure but also through the two objects, that is, the liquid containing the object to be measured and the container.
- the liquid containing the object to be measured and the container since liquids and containers reflect and absorb electromagnetic waves, there are problems such as a weak transmitted electromagnetic wave signal and complicated analysis of obtained data.
- Patent Document 1 and Patent Document 2 when the number of measurements and the types of objects to be measured are large, a new gap arrangement structure is prepared for each measurement, and the objects to be measured are attached. It was necessary to perform pre-processing.
- dimensional variation of the gap arrangement structure can be considered.
- Such an error factor has a particularly large influence when the amount of the object to be measured is small and the change in frequency characteristics is slight. Note that the dimensional variation of the gap arrangement structure increases in the order of the same gap arrangement structure, the individual void arrangement structures, and the production lots of the gap arrangement structures.
- An object of the present invention is to provide a high-sensitivity measurement device that can perform measurement and a method for measuring characteristics of an object to be measured using the device.
- the present invention is a measurement device comprising: a device main body having at least one recess for accommodating a specimen including an object to be measured; and a void arrangement structure having a plurality of voids penetrating in a direction perpendicular to the main surface.

- the gap arrangement structure including one effective area disposed inside each of the plurality of recesses is provided, and the gap arrangement structure includes a plurality of the insides of the plurality of recesses. It is preferable to be fixed to the device main body so that each of the effective areas is located.
- the device body includes a first member and a second member, and the gap arrangement structure is sandwiched between the first member and the second member.
- the gap arrangement structure includes a frame member for holding the gap arrangement structure, and the gap arrangement is performed by fitting the frame member with the first member and the second member. It is preferable that the structure is sandwiched between the first member and the second member.
- the material of the said device main body contains a magnetic body.
- the measurement device irradiates the measurement device with electromagnetic waves, and detects the frequency characteristics of the electromagnetic waves forward scattered or back scattered by the gap arrangement structure, thereby determining the characteristics of the object to be measured included in the specimen. It is preferably used for measuring.
- the present invention is a method for measuring characteristics of an object to be measured using the measuring device, A first step of accommodating a specimen containing the object to be measured in the recess; A second step of removing the void arrangement structure from the device body; Irradiating the gap arrangement structure with an electromagnetic wave, and detecting the frequency characteristic of the electromagnetic wave forward scattered or back scattered by the gap arrangement structure, thereby measuring the characteristic of the object to be measured included in the specimen. Steps, It also relates to a method for measuring characteristics of an object to be measured.
- the volume of the recess for accommodating the specimen containing the object to be measured can be reduced, a small amount of specimen (liquid containing the object to be measured) is not required, and a small amount can be obtained. It is possible to realize a highly sensitive measurement that can measure the characteristics of the object to be measured with the specimen.
- the measurement can be performed in a state where the void arrangement structure is separated from the specimen and the container, so that it is not affected by the specimen or the container. Highly sensitive measurement can be realized.
- the measurement device of the present invention includes a plurality of concave portions arrayed, even if the number of times of measurement and the type of object to be measured are large, simultaneous work is possible, so the work time can be reduced, Measurement throughput can be improved. Further, a process of cleaning the inside of the container for each type of object to be measured is not required, and the risk of biohazard is reduced.
- the measurement device of the present invention has a structure in which each part of one common gap arrangement structure is arranged inside a plurality of recesses, so that the dimensional variation between production lots and individuals of the gap arrangement structure The measurement error due to this can be reduced, and highly sensitive measurement can be realized.
