The present claimed invention shortens cleaning time of a container of a sample dispersing device and reduces variation of a cleaning state. The present claimed invention is a sample dispersing devicethat disperses a powder sample (W) on an upper surface of an analytical memberand that comprises a containerthat has a placing surfaceon which the analytical memberis placed, an introducing mechanismthat introduces the powder sample (W) into inside of the container, and a covering memberthat covers an inner surface of the containerand that can be attached to and removed from the container

Sample dispersing device and sample dispersing method

A sample dispersing device contains a container inside of which a dispersal chamber where a power sample is dispersed is formed, and an introducing mechanism that introduces a gas containing the powder sample from the outside of the container into the dispersal chamber based on a pressure difference between the inside and the outside of the container. The introducing mechanism contains an introduction pipe where the gas containing the powder sample flows, and several restrictors arranged in the introduction pipe.

Sample dispersing device

The radiation detection device according to the present invention comprises: a sample holding unit; an irradiation unit configured to irradiate a sample held by the sample holding unit with radioactive rays; a detection unit configured to detect radioactive rays generated from the sample; a distance calculation unit configured to calculate a distance from a predetermined base point to an irradiated part, which is to be irradiated with radioactive rays, of the sample held by the sample holding unit; a size specification unit configured to specify a size of the irradiated part on the sample based on the calculated distance; and a display unit configured to display the specified size of the irradiated part.

Radiation detection device and computer program

The radiation detection device is equipped with a sample holding unit; an irradiation unit for irradiating a sample held on the sample holding unit with radiations; a detection unit for detecting the radiations generated from the sample; an illumination unit for irradiating the sample with light; an observation unit for observing the sample; and a light transmitting plate for allowing the light from the illumination unit, with which the sample held on the sample holding unit is irradiated, to be transmitted therethrough. The light transmitting plate is disposed at a position between the sample holding unit and the irradiation unit, and has an opening portion for allowing the radiations from the irradiation unit, with which the sample is irradiated, to pass therethrough and a scattering portion for scattering light.

Radiation detection device

A sample dispersion device capable of preparing a measurement sample in the most suitable dispersion state without repreparing the measurement sample many times, is one that by introducing sample particles into a container and injecting the sample particles in the container using a pressure difference, disperses sample particles onto a holding member provided in a container to make the holding member hold the sample particles. The holding member has a holding surface made to hold the sample particles; and the holding surface has multiple portions having mutually different tilt angles.
