Abstract: [Object] For a glycated protein sensor provided with an immobilized enzyme, a technology for increasing measurement accuracy and the stability of the glycated protein sensor is essential. Unfortunately, there are no known enzymes that can increase the accuracy and stability of measurements that use a glycated protein sensor. [Solution] The present invention provides a fructosyl amino acid oxidase, and a residual activity exhibited by the fructosyl amino acid oxidase after being treated at a temperature of 65°C to 80°C for 20 minutes while being immobilized on a support is 70% or greater. The present invention also provides a glycated protein sensor and a method for measuring a glycated protein.

Abstract: An electrochemical gas sensor (1) as an embodiment of the present invention comprises an insulating substrate (10), an electrolyte layer (11) formed on the insulating substrate (10), a first metal layer (12) formed on the insulating substrate (10), and a second metal layer (13) formed on the insulating substrate (10) so as not to contact the first metal layer (12). The electrochemical gas sensor (1) also comprises a working electrode (20) formed covering the electrolyte layer (11) and the first metal layer (12) on the insulating substrate (10) so as to extend over the electrolyte layer (11) and the first metal layer (12), and a counter electrode (21) formed covering the electrolyte layer (11) and the second metal layer (13) so as to extend over the electrolyte layer (11) and the second metal layer (13).

Abstract: The invention refers to an electrochemical process measurement arrangement (10) with a process sensor unit (30), the sensor unit (30) comprising a reference electrolyte tank (50) with a reference electrolyte liquid (52) and a reference electrode (54), and a measurement electrolyte tank (60) with a measurement electrolyte liquid (62), a measurement electrode (64), a gas-selective membrane (90) separating the reference electrolyte liquid (52) from a sample liquid (13') and a pressure balance channel (84) fluidically connecting the tank interior (56) with the atmosphere (11).
The pressure balance channel (84) is defined by a balance channel body (80) made of a hydrophobic material having a contact angle Theta higher than 90°.
This allows to realize a very narrow pressure balance channel without the danger of being clogged by electrolyte droplets, so that the evaporation loss of the measurement electrolyte is significantly reduced.

Abstract: An object is to provide a micro-analysis chip in which a satisfactory area of contact between a specimen and an ion-selective membrane and an adequate amount of the specimen that reacts with the ion-selective membrane can be secured, and which is excellent both in measurement sensitivity and in ion selectivity. In order to achieve the object, a micro-analysis chip as described below is provided. That is, provided is a micro-analysis chip including a channel region which is surrounded by a channel wall provided inside a porous substrate. The channel region includes a first channel chamber containing a reference electrode, a second channel chamber containing a working electrode. The working electrode is covered with an ion-selective membrane containing an ingredient that has ion selectivity. The ion-selective membrane has an exposed surface serving as a dispensing section to which a specimen is dispensed.

Abstract: Procédé de détermination en aval d'une chambre (12) de pressurage d'un pressoir (11), de la nature de jus produits au moins par pressurage de raisins dans ladite chambre (12) de pressurage en vue de distinguer les jus issus de la zone de la pulpe des grains de raisin des jus issus de la zone de la pellicule des grains de raisin, ledit procédé comprenant au moins une étape de mémorisation d'une valeur de pH de consigne et une étape de mesure en temps réel et en continu du pH des jus collectés en aval de la chambre (12) de pressurage au moins jusqu'à obtention de ladite valeur de pH de consigne mémorisée.
Ledit procédé comprend, avant l'étape de mémorisation de ladite valeur de pH de consigne, une étape de mesure du pH et de la conductivité des jus collectés en aval de la chambre (12) de pressurage pour enregistrer un couple de valeurs pH/conductivité et une étape de détermination de la valeur de pH de consigne à mémoriser en fonction du couple pH/conductivité mesuré.
