An automatic analyzer is provided which is capable of detecting contact of a distal end of a probe with a liquid level even if capacitance between the container and the probe is excessively increased. The automatic analyzer for analyzing a sample includes: a container that contains liquid; a probe that aspirates the liquid; a capacitance measuring unit that outputs a voltage according to capacitance between the container and the probe; a determining unit that determines, based on the voltage output from the capacitance measuring unit, whether or not a distal end of the probe contacts the liquid; and a capacitor that is installed between the capacitance measuring unit and either the probe or the container.

To achieve efficient filtration, a first liquid holding portion (101) is provided for holding a liquid. A first hole (411) is disposed at a bottom surface of the first liquid holding portion (101), and a second hole (421) is disposed at a surface of the first liquid holding portion (101), the surface being separate from the bottom surface. A second liquid holding portion (201) is in communication with the first liquid holding portion (101) through the first hole (411), and a third liquid holding portion (301) is in communication with the first liquid holding portion (101) through the second hole (421). A first filter (412) is disposed at the first hole (411), and a second filter (422) is disposed at the second hole (421).

To estimate a defective consumable from among a plurality of consumables in a plunger pump, or to estimate a defective plunger pump from among a plurality of plunger pumps. A liquid chromatograph 100 includes: a double plunger pump 6 including a first plunger pump 9a, a second plunger pump 10a, and a plurality of consumables 11a to 14a; a pressure sensor 8a configured to detect a pressure of a solvent discharged by the double plunger pump 6; a dispensing unit 2; a separation column 3; and a control unit 16 configured to estimate a defective consumable among the plurality of consumables based on a first pressure detected by the pressure sensor 8a in a first section in which the first plunger pump 9a discharges the solvent into a flow path 101 and a second pressure detected by the pressure sensor 8a in a second section in which the second plunger pump 10a discharges the solvent into the flow path 101.

Provided is an automatic analyzer and a method of cleaning a nozzle in an automatic analyzer capable of more effectively cleaning a dispensing portion while reducing contamination caused by splashes as compared with the related art. The automatic analyzer includes: a first cleaning portion 52 configured to discharge first cleaning water from a first direction with respect to a tip of a sample dispensing probe 21; and a second cleaning portion 54 configured to discharge second cleaning water from a second direction opposite to the first direction with the sample dispensing probe 21 interposed therebetween with respect to the tip of the sample dispensing probe 21. A first range where the first cleaning water hits the tip of the sample dispensing probe 21 and a second range where the second cleaning water hits the tip of the sample dispensing probe 21 are shifted in one or both of a vertical direction and a horizontal direction.

An information processing device of an automatic analysis system determines, based on operational data related to an operation of the automatic analyzer 100 stored in an operation database 32, suitability of a system parameter 31 for an actual operation of the automatic analyzer, and creates, when the system parameter is determined to be unsuitable, a recommended system parameter 33 to eliminate the unsuitability. Accordingly, it is possible to eliminate a malfunction in an automatic analyzer without a user performing a manual operation or requesting a serviceman.

A device stores a corrector that creates a reconstituted image from an inputted image in accordance with a set parameter. The adjustment of the set parameter is performed such that a first reconstituted image created by the corrector from an inputted first image and a second image that is the same object as the first image and differs from the first image in color tone are brought close in shape to each other. The device creates a reconstituted image of the target image by inputting the target image to the corrector. The creation of a reconstituted image of the object image by a corrector is performed such that, in accordance with a set parameter, a feature amount is extracted from an inputted image, the extracted feature amount is corrected, and the reconstituted image of the object image is created from the corrected feature amount.

It is an object of the present invention to provide a transport device, which allows, with compact structure, transportation of the transport object with a variety of protrusion. Accordingly, the present invention provides a transport device for transporting a transport object having a protrusion that protrudes from a flat base, and includes a plurality of grip units for gripping the transport object while having the grip unit pressed against a base surface of the transport object. At least one of the grip units has a shape to cover at least a part of a side surface of the protrusion without covering a leading end surface of the protrusion. For example, the shape corresponds to a notch shape along the side surface of the protrusion in a circumferential direction.
