A purpose of this invention is to provide an electrode that is extremely preferably used for measuring a pH of a cell culture medium. This electrode is designed to be inserted into an insertion bore arranged on a container into which a sample solution as being a measuring object is put, and comprises an internal electrode, a storage that houses the internal electrode, a gelled or liquefied internal liquid that is filled into the storage so as to contact the internal electrode, and a sensor part that is electrically connected to the internal electrode through the internal liquid and arranged at a distal end surface of the storage as to detect a electric potential of the sample solution. The storage has a positioning surface for positioning the storage at a mounting position at which the inner wall surface of the container and the distal end surface of the storage are on the same plane.

Electrode, composite electrode, and analyzer for analyzing liquid

To maintain a uniform etching rate during cleaning of a responsive glass in a glass electrode, a responsive-glass cleaning liquid for a glass electrodeserves to clean a responsive glassused in the glass electrode, is used with a hydrated-layer forming solution for forming a hydrated layer on the surface of the responsive glass, and contains ammonium hydrogen fluoride having a predetermined concentration, or a salt of a strong base containing hydrofluoric acid and a fluoride ion.

The electrode assembly is provided with: a rod-like bodythat extends along a predetermined axis; a substrate that is formed with a through-hole penetrating between a front surface and a back surface and attached to a fore end part of the body; and a sensor chip for electrochemical measurement, which is attached on the back surface of the substrate such that a sensing part is exposed outside from the through-hole, wherein: on the back surface of the substrate, a wiring for obtaining an output signal from the ISFET chip is formed, and the sensor chip is attached to the wiring directly or closely; and the substrate is attached with being inclined with respect to the predetermined axis of the body, and thereby the front surface of the substrate forms at least a part of a fore end surface that is inclined with respect to the predetermined axis.
