Abstract: An electrolyte analysis device includes a substrate extending in one direction, a main base portion provided on a main surface of the substrate, an ion selective film provided to be in contact with the main base portion so as to cover the main base portion, and an auxiliary base portion provided on the substrate. In a state where the electrolyte is in contact with a side of one end of the substrate so as to cover the side of the one end, a peeling determination unit obtains a potential of the main base portion and a potential of the auxiliary base portion, respectively. Whether or not the ion selective film is peeled from the main base portion is determined based on a potential difference between an obtained potential of the main base portion and an obtained potential of the auxiliary base portion.

Abstract: To provide a technology that can suppress an operation unintended by a user caused by an erroneous operation by the user. An electrochemical sensor according to one aspect of the present invention is for measuring a concentration ratio between sodium ions and potassium ions in a liquid to be measured that includes: a sensor head; and a calculation unit that allows performing a calibration operation and a measurement operation. The calibration operation calculates a characteristic parameter of the sensor head based on sensing data of the sensor head in a state where the sensor head is brought into contact with a calibration agent. The measurement operation calculates the concentration ratio based on the characteristic parameter of the sensor head and the sensing data of the sensor head in a state where the sensor head is brought into contact with the liquid to be measured.

Abstract: A separating method includes holding a combined substrate and separating a first substrate. In the holding of the combined substrate, the combined substrate in which the first substrate and a second substrate are bonded is held. In the separating of the first substrate, the first substrate is separated from the combined substrate, starting from a side surface of the combined substrate. The separating of the first substrate includes brining a fluid containing water into contact with the side surface.

Abstract: In a joint apparatus, a transfer region and a processing region are formed. In the transfer region, a transfer mechanism transferring a first substrate, a second substrate, or a superposed substrate, a position adjusting mechanism adjusting an orientation in a horizontal direction of the first substrate or the second substrate, and a reversing mechanism reversing front and rear surfaces of the second substrate are provided. In the processing region, a first holding member mounting and holding the first substrate on an upper surface thereof, a second holding member holding the second substrate on a lower surface thereof, and a pressing and moving member bringing one end portion of the first substrate and one end portion of the second substrate into abutment with each other and pressing the one end portions when joining the first substrate and the second substrate together are provided.

Abstract: A joint system includes: a transfer-in/out station capable of holding a plurality of substrates or a plurality of superposed substrates, and transferring-in/out the substrates or superposed substrates to/from a processing station; and the processing station performing predetermined processing on the substrates and joining the substrates together.
