One mode of an optical inspection apparatus according to the present invention is an optical inspection apparatus for optically inspecting an object, the optical inspection apparatus including: a biasing section () configured to apply, to a group of objects (A) on a stage, a force for moving the group of objects away with respect to the stage (); a catching section () including an adhesion portion () to which an object in the group of objects moved from the stage adheres; and an analysis section () configured to optically analyze the object caught by the catching section. This makes it possible to efficiently and satisfactorily perform optical analysis of individual microplastics by eliminating manual work of picking up the microplastics one by one.

Optical inspection apparatus and optical inspection method

A light source emits excitation light to discharge gas that flows through a dielectric tube. A ground electrode unit includes a first ground electrode and a second ground electrode arranged at a distance from each other in an axial direction of the dielectric tube. A high-voltage electrode is provided between the first ground electrode and the second ground electrode. A first distance between the first ground electrode and the high-voltage electrode is shorter than a second distance between the second ground electrode and the high-voltage electrode. A cover is provided on an outer wall of the dielectric tube at a position between the first ground electrode and the high-voltage electrode. The light source is arranged to emit excitation light such that an optical axis thereof is directed toward a position where the cover is not provided on the outer wall of the dielectric tube.

Dielectric barrier discharge ionization detector and gas chromatography analyzer

According to one embodiment of the present disclosure, provided is a learning system that updates a parameter for a neural network, the learning system including: a plurality of differential value calculators; and a parameter update module.

Learning system and learning method

A gas chromatograph includes a column module for independently adjusting the temperature of a separation column. The column module is held by an oven with the separation column being horizontal. The column module includes the separation column for separating a sample gas into components, a column accommodating member accommodating inside the separation column while surrounding the separation column by a heat insulating member, and including a gap between the separation column and the heat insulating member for air to flow along the separation column, and a heater, provided inside the column accommodating member, for heating the separation column by being in direct or indirect contact with the separation column. The column accommodating member includes an air inlet port for introducing external air into the gap between the separation column and the heat insulating member, and an air outlet port for exhausting air in the gap.

Gas chromatograph device

A flow channel module comprises a flow channel plate, a flow channel connection block, and a pressing mechanism. The flow channel plate is provided with a main body and a protrusion section protruding in the circumferential direction from the peripheral edge of the main body, the protrusion section having a port communicating with an inner flow channel. The flow channel connection block is provided with a concave section for being engaged with the protrusion section and having inside a port facing surface for facing the port, and an outer flow channel connection section that is connected to the port facing surface by a flow channel. The pressing mechanism is configured to press the protrusion section inserted in the concave section and the port facing surface against each other so that the flow channel and the port are connected while maintaining air tightness or liquid tightness.

Flow channel module and chromatograph provided with the flow channel module

A gas chromatography device includes a sample injection part, a detector, a separation column, and a transfer line connecting between the sample injection part and the separation column and between the sample injection part and the detector. Furthermore, a column temperature adjustment part for adjusting the temperature of the separation column, and a line temperature adjustment part for adjusting the temperature of the transfer line are provided. The line temperature adjustment part is structured to include a heat block which includes a heating element and which is in contact with the transfer line from one side, and a holding member which presses the transfer line toward the heat block side by being in contact from the other side, and to sandwich the transfer line by the heat block and the holding member.

Gas chromatography device

A gas chromatography equipment includes a sample introducer, a detector, a column module, and an oven including a housing. A sub-space is provided in a projection section projecting downward from a portion of a bottom face of the housing communicates with a main space of the housing. A column module attaching section is provided outside the housing and below the main space. A fixed side face, which faces the column module attaching section, of the projection section serves as an attachment face for attaching the column module. The column module is attached to the housing in such a way that the main flat surface of the column module is horizontally positioned with an end face of the column module being the attachment face.

Gas chromatography equipment

Provided is a plate-type column which allows the temperature of its inner passage to be rapidly increased or decreased while ensuring the correctness of an analysis or other operations. A plate-type columnincludes: a plate-shaped main body; projecting portionsandprotruding from a circumferential edge of the main body; and a fluid-flow passageextending in the main bodyand the projecting portionsand. An intermediate portion of the passageis provided in the main body, while each of the end portions of the passageextends from the main bodythrough the projecting portionor, with each of the end portions being open to the outside at the tip of the projecting portionor

Plate-type column, temperature regulation system and gas chromatograph system

A housing of a column unit is tubular-shaped, and includes a first opening and a second opening, and an inner space separated from outside air by an insulating material. An air cooling section including a cooling device is arranged on a side of the first opening of the housing. At the time of cooling the inside of the inner space of the housing, air is caused, by a fan, to flow through the air cooling section and from the side of the first opening to a side of the second opening. A column section including a separation column and a heater is arranged inside the housing. A gap through which air flows from the first opening to the second opening is formed between the column section and an inner wall of the inner space of the housing.
